Background Information:

  We are currently writing about 1MB per second of data, and creating 
and deleting about 600+ inodes per second.  The following OOPS shows 
that the problem occurs in the 2.4.20-18.7smp kernel.  Tracing the code, 
it appears that if inode_has_buffers(inode) returns true then the BUG is 
thrown.

We are running with ext3 fs, and my guess would be that the problem 
exists in one of the following situations:

  The process grows, to the point where it is using more memory, and it 
tickles something in the virtual memory which corrupts the 
inode->i_dirty_buffers list so that the i_dirty_buffers are in fact not 
empty.  ( This is a conjecture based on the fact that the ext3 
journaling doesn't store the i_dirty_buffers info with the inode itself ).
 
  The other possibility is that such a high I/O rate is somehow 
corrupting the journaling, causeing the same type of issue.

Any hints/suggestions/input  would be appreciated.

Thanks

Its a good idea to file Red Hat kernel bugs in
https://bugzilla.redhat.com

The Red Hat kernel does differ from the base kernel and 
the Red Hat folks tend to knwo those differences best

The long delay is due to retries, probably driven by mount.nfs.

But looks like there's a 10 second delay between each attempt.
Maybe that's OK.

It did take quite a long time to exit:

[root@scs000128074 kolga]# time mount -o vers=4.2,sec=sys,xprtsec=tls

No doubt.

That's what I was looking for. I wanted to know if it was
Linux NFSD doing this.

Jakub asked that NULL checking be removed from handshake_req_cancel,
or at least that's what I read into his comment. That choice is
definitely flushing bugs.

So this crasher is familiar. req_cancel is getting called in some
scenario where the socket or request is partially filled in. We
have to figure out how that's happening.

If debug info is a problem, then just add a sarcastic quantity of
NULL checks in handshake_req_cancel, rebuild, and it should tell
you exactly which pointer is bad.

BPF might also be a solution, but I'm not sure if it relies on
debug info. Might be only BTF is needed.

I'm not sure what kind of a reason you are looking for. I think the
server can send an RST at any point in a TCP connection and the client
shouldn't crash. But the real reason is probably because the server's
code is getting developed and they ran into some error and resetting
the connection.

I apologize I don't have that info and I'm working on trying to figure
out how to get this information to you. Lab kernels are built with
CONFIG_DEBUG_INFO disabled and thus I can't do faddr2line. I will
attempt to build on with debugging enabled (has been problematic
before for the lab machines so not sure if that'll be successful I
might have to hack the linux kernel to simulate the reset).

Hi Chuck,

I've updated the kernel code to the latest  commit
46588cade103b446f74a7ee160a83cd2a80399e7 (HEAD ->
chuck-rpc-with-tls-04032023, chuck/topic-rpc-with-tls-upcall) but the
client is still crashing but looks like in a different place. This
happens when the server terminates the connection (immediately) as the
tls handshake happens.

Here's the stack trace:

Update and retry. It has a familiar ring, but I can't say I've
seen this recently.

Hi Chuck,

Have you seen this oops? This is not my testing so all I know was that
it was an attempt to mount with xprtsec=tls (against ONTAP).

OK, I followed the advice [1] - "I would prefer to see is one submission,
then two or three days (so the first submission has had some bake time),
then the next one and it should assume the first is applied."

And submitted the fix [2].

Isn't fixing random kernel memory corruption triggerable by userspace
exactly the sort of thing we should be rushing into Linus's tree?

Yep this looks like it.

FWIW, it causes random kernel memory corruption and failures in my
experience, I was very lucky to get such a clean oops the first time..

Digging a bit, we found a fix that might be related to this issue.
I would be happy if you could try that and report if it solved this problem.
We plan to send it soon.

commit 1d4ecbf034193f000fe6686586c40ab4b2a95da1

    IB/uverbs: Fix device cleanup

    Uverbs device should be cleaned up only when there is no
    potential usage of.

    As part of ib_uverbs_remove_one which might be triggered upon reset flow
    the device reference count is decreased as expected and leave the final
    cleanup to the FDs that were opened.

    Current code increases reference count upon opening a new command FD and
    decreases it upon closing the file. The event FD is opened internally
    and rely on the command FD by taking on it a reference count.

    In case that the command FD was closed and just later the event FD we
    may ensure that the device resources as of srcu are still alive as they
    are still in use.

    Fixing the above by moving the reference count decreasing to the place
    where the command FD is really freed instead of doing that when it was
    just closed.

Hi,

Thanks for informing :)
We'll try to debug that, but I expect we'll only get to that by end of
next week.

Thanks,

Matan,

I suspect your reworking series broke hot removal, I get a kernel oops
when removing modules on 4.13-rc2.

I think it is some kind of race with uverbs being removed concurrently
with user apps closing uverbs. In this case I removed umad first which
caused systemd to forcibly shutdown srp_daemon, which happened
concurrently with the rmmod of ib_uverbs.

* Kernel oops

I have retried compiling the 3.4 Kernel this time in Squeeze. The
Kernel compiles fine and will boot up to 255 cores; however, after
that if fails out with the following Kernel oops when booting more
than 255 cores (Kernel is compiled with 512). Here is the boot log
with the option bootmem_debug=1. I have tried to shorten the boot log
and leave what I think are the important parts; however if anyone
needs the 35M boot log then I will gladly send as attachment.

It looks like after Node 64 which would be cores 256 and up, it can
not find start_pfn and
it shows 0 total pages. The instruction pointer is at
[__copy_user+0x891/0x950].  In the meantime I
have compiled the 2.6.35 Kernel with support for 1024 CPUs that works
as a hold over. Anyone have any ideas as to why it is failing out at
this point?

Thanks,

Hi, all.

Mr. Stanislav Kinsbursky suggests me send you a report about an oops I encountered in the past few days.

A few days ago, I tested some VMs with NAT enabled under KVM and libvirt, but kernel crashed when I shut down these VMs, though this issue did not occur every time. I did some search and found a webpage(http://www.spinics.net/lists/netdev/msg193846.html) in which Simon reported a similar issue.

The operating system I use is gentoo-amd64 with no-multilib profile, kernel version is 3.4.0, libvirt-0.9.13 with USE flag "qemu virt-network" enabled and qemu-kvm-1.0.1-r1. Here are the steps to reproduce:

1. Let's define that starting a VM with NAT enabled under KVM and libvirt and then shut it down immediately as one operation.
2. Repeat the operation for several times.

I also did 3 tests:

Test 1: 
The host machine is with a regular linux 3.4.0 kernel, and the VM had NAT enabled. Kernel crashed after 2, 7 and 13 operations.

Test 2:
The host machine is with a regular linux 3.4.0 kernel, and the VM had no network access. No crash occured after 100 operations.

Test 3:
The host machine is with a linux 3.4.0 kernel, but drivers/net/tun.c was reverted back to just before commit 1ab5ecb90cb6a3df1476e052f76a6e8f6511cb3d (https://github.com/torvalds/linux/commit/1ab5ecb90cb6a3df1476e052f76a6e8f6511cb3d#drivers/net/tun.c), (or you can use a tun.c from a 3.2.0 kernel, according to Simon's report), and the VM had NAT enabled. No crash occured after 100 operations.

Moreover, I observe that a virtual interface is created to handle network access when a VM with NAT enabled starts, and the virtual interface is removed when the VM is shut down. Crashes usually occur at the time the virtual interface is removed.

Finally, 3 types of kernel crash traces were observed; and thanks to rsyslog, they are all recorded:

Type 1:

Hi, all.

Mr. Stanislav Kinsbursky suggests me send you a report about an oops I encountered in the past few days.

A few days ago, I tested some VMs with NAT enabled under KVM and libvirt, but kernel crashed when I shut down these VMs, though this issue did not occur every time. I did some search and found a webpage (http://www.spinics.net/lists/netdev/msg193846.html) in which Simon reported a similar issue.

The operating system I use is gentoo-amd64 with no-multilib profile, kernel version is 3.4.0, libvirt-0.9.13 with USE flag "qemu virt-network" enabled and qemu-kvm-1.0.1-r1. Here are the steps to reproduce:

1. Let's define that starting a VM with NAT enabled under KVM and libvirt and then shut it down immediately as one operation.
2. Repeat the operation for several times.

I also did 3 tests:

Test 1: 
The host machine is with a regular linux 3.4.0 kernel, and the VM had NAT enabled. Kernel crashed after 2, 7 and 13 operations.

Test 2:
The host machine is with a regular linux 3.4.0 kernel, and the VM had no network access. No crash occured after 100 operations.

Test 3:
The host machine is with a linux 3.4.0 kernel, but drivers/net/tun.c was reverted back to just before commit 1ab5ecb90cb6a3df1476e052f76a6e8f6511cb3d (https://github.com/torvalds/linux/commit/1ab5ecb90cb6a3df1476e052f76a6e8f6511cb3d#drivers/net/tun.c), (or you can use a tun.c from a 3.2.0 kernel, according to Simon's report), and the VM had NAT enabled. No crash occured after 100 operations.

Moreover, I observe that a virtual interface is created to handle network access when a VM with NAT enabled starts, and the virtual interface is removed when the VM is shut down. Crashes usually occur at the time the virtual interface is removed.

Finally, the attachment contains the config file I use to compile the kernel and the kernel crash traces. I am sorry that my laptop does not have a serial port, I could not provide traces from tty console. Hope these could help.

Sincerely,

Zhijie

Hm, I thought I took a patch to fix this a few weeks ago.

Oliver, have I missed anything recently?

Hi,

Latest -git seems to have the same problem, and this was about three
weeks ago, so.. Ping?

This shouldn't be too hard; the code is trying to unlock the mutex
&acm->mutex even when "acm" is NULL. It seems that the label "err_out"
is otherwise unused, so it makes sense to move this one step further
down, so that it doesn't try to unlock the non-existant mutex.

If the problem is reproducible, you could try the patch below!


Vegard

PS: I actually think the code has some other problems too. Shouldn't
&acm->mutex be locked before we even inspect acm->dev?

Sorry.
After i ran ldconfig oops has been added to dmesg and ldconfig crashed
with segmentation fault. (ldconfig activate oops). There is another
applications which crashes and oops apper in dmesg (paludis - gentoo
package manager)
Now I am back in kernel 2.6.22-r10 and all is ok.

  To: linux-kernel

this has occured a couple of times. i was editing a unicode file with
vim in the console. after a reboot, i immediately tried to do just that
again and it crashed. it might have occured upon trying to select some
text with the mouse (gpm) or trying to delete characters from the file.

	regards,

	andrej

Do you have a test case that can reproduce this?

If so please file a bug
http://oss.sgi.com/bugzilla
and attach the test program.

Include any other relevant info.

* Kernel Oops

Hello,

I'm working for the french national education.
We work on a server for students since 3 years.
The solution is based on a Mandrake 9.1 but with a large number of updates.
Our kernel is : 2.4.32 and the xfstools are updated :
- xfsdump-2.2.42
- xfsprogs-2.8.11
- libxfs1-2.8.11
We made a tool  to create students and about 1 time over 10 we have a 
kernel Oops.
With the same data we can reproduce the crash and it always append at 
the same place (the same student).
It was the same 2 years ago with older kernel and xfs releases but we 
hadn't enough student databases to test.  Now, the project is growing 
and the number of crashes in schools too !

The user creation process is composed with :
mkdir, setfacl, chown, setquota for a pam-ldap authentification.

The Oops usually happends on the chown instruction but if we remove it, 
it happends on the setquota instruction which is one line behind.

Cheers,

Joël Cuissinat

I'd be suspecting that 0x04000000 should have been 0x00000000: a single bit

That's all the info I have at the moment. The server is still running. I 
tried trying to reboot it by typing reboot and it keeps running. 
Services won't shut down. But it's still processing email and filtering 
spam.

It appears to be a Kernel Oops ($subject), but there's not
enough of it listed here to determine what happened.

IMO, it's worthwhile to iron out the NFS problem, but you'll likely find
that native rsync, rsync over ssh or rsync over rsh will be much faster
than rsync+NFS.  If you have to do rsync+NFS, you might want to use --
whole-file.

* Kernel Oops

From: Chris Penney @ 2005-04-25 16:31 UTC (permalink / raw)
  To: nfs

I have a 2.6.11.5 NFS server that serves a directory /s that had light
to moderate activity.  I had another file server mounted as /nicfs7
and was doing a local rsync (moving some data) from /s/path to
/nicfs7/path when (for some unknown reason) it hung.  I hit ctrl-c and
then kill -9'ed the two remaining rsync processes.  I then unmounted
/nicfs7 (which seemed ok right after).  I then saw what I pasted in
below in messages.

At this point NFS service seems ok; however, one of the nfsd threads
is missing.  I specify to start 128 and only 127 are running.  Is a
missing nfsd a problem?  It's no clear to me why an nfsd did in the
first place either when I was using nfs client -> local disk.

   Chris

i've compiled a non PREEMPT kernel, and the oops still appears
i'am using kernel 2.6.7
a have a VPN server with pppd and pptpd(poptop) and and average of 130
simultanious connections, the oops doesn't occur at a particular number

Nasty slab corruption.  Is it repeatable?  I'd be suspecting the bttv
operation is the cause - if you repeat that operation does the system again
fail?

Please find the attached text files containing 2.6.10
kernel Oops messages 
sent out by the kernel to via the serial port.  The
2.6.10 kernel was 
compiled with all debugging support enabled.  It was
running on a Gentoo 
machine.

At the time of the Oops, one process was doing
iterations of capturing 100 
frames each via BTTV and another was tar untarring a
huge file.

Please let me know what other information you require
and/or if this should 
be sent to other people/organizations/mailing lists.

Thanks,
Marat

No, it only happened once so far, of at least one hundred policy reloads
on systems with loaded nvidia driver. So it is not a very big issue for
me; I wanted to post it so people know about it.
I am very happy with the stability of my SELinux systems. :-)

> P.S. we should to exchange GPG keys

Good idea. I'll mail you separately about this.

Thanks,
Thomas

Not just with a loaded nvidia driver, but with nvidia in the call trace.
(I'm no kernel expert at all. it looks a bit like an interrupt occured
while transferring the policy to kernel space, that got handled by the
nvidia driver. but that is just a guess.)

Does it happen frequently? If so, try without preempt enabled.

P.S. we should to exchange GPG keys; i'm at IFI, too, and i've got a
strongly connected key. Although i havn't met rjc or colin yet in person
i do only have a path distance of 2 to them, often with multiple links
(well, the debian crowd loves keysigning...)

Greetings,

I realize that this oops report may be almost useless because it
happened on a system with loaded nvidia binary driver. Nevertheless,
maybe one of the kernel gurus can tell if SELinux is at fault here or if
I should blame nvidia.
The oops happened on a vanilla 2.6.8.1 box while loading policy. After
the oops, load_policy hang in D state.

Here is the oops:

No.

By the way, I can tell, that I recently got the following message
printed on a shell I opened, just before it crashed (handwritten from
screen (keyboard was locked)):

Assertion failure in __journal_file_buffer() at
fs/jbd/transaction.c:1934: "jh->b_transaction == transaction ||
jh->b_transaction == 0"

It's a bit strange that no registers have a value vaguely like
0x1841b518, but at a guess I'd say that you have a bad ->owner
pointer in a /proc inode.

What modules are you using, and had any modules been rmmod'ed prior
to the crash?

I get the attached oops message in syslog on my 2.6.6 kernel. I have
also attached the ksymoops output.

When the oops has occured, I cannot open any shell (including a login
shell).

Ok, we've patched all systems and the oops seems to have gone.
Great (and especially really fast) done, thanks!

Systems (a bit outdated, ok...)
Pentium MMX 200, Intel 430TX, IDE, vanilla 2.6.3
Pentium MMX 233, Via Apollo VP2, IDE, vanilla 2.6.3
Pentium II 450, Intel 440BX, SCSI, vanilla 2.6.3

All with noACPI, PREEMPT, APIC and Debian Sid.

It seems that's something to do with preemtion... that's
all I can guess. Kernels <= 2.6.2 are doing very well
(with PREEMPT enabled)

Any hints?


ciao, phb

The usbscanner driver is obsoleted, marked as broken, and removed
completely in the -mm tree and my usb tree.  Those changes will get sent
to Linus in a day or so.

In short, don't use this module, it's known to be broken and not needed.

thanks,

Hi !

I've got this kernel oops with 2.6.3-rc1 when I remove an usb 
peripheral. The result is the same if USB UHCI is compiled statically or 
in module.
Please find in attachment the output of lspci and .config

Best regards,

Mathieu LESNIAK

Hi

I don't know what is causing your problems, but I can give you an advice or two.

* 2.4.21 isn't the lastest stable kernel - try upgrading to 2.4.22 and see if your problems clear.

* Your hardware may be causing you trouble. Try inserting other memory-modules etc.

I wish you good luck!

Hi,

My linux box keeps crashing every 24 hours or so. It's running kernel 
version 2.4.21. I ran the oops message through ksymoops and got this result:

Seems the problem has gone by using the original Debian kernel 2.4.18...
Reading a little bit the different changelog of kernel between 2.4.18
and 2.4.21, it seems that there are some vm change incorporated (from
-aa)...but I'm not an expert at all.

Another thing is that the load is about 2 or 3...

I hope somebody will have an idea off what's going on...

Have fun,

Hello all,

I've just add two hangs with a plain vanilla kernel 2.4.21 on a Debian
woody up2date. The machine is an old Pentium 100 with 64 Mb. Softs
running on this machine are :
- Apache+PHP+mod_ssl+...
- Sendmail+spamassassin
- Mailman (This can explain the python)
- proftpd
- squid

I have installed gallery for fotos and while adding many big photos at a
time  (the process is quite consuming... the CPU is 100% during this).
The problem seems to not occur when adding photo by photo

What is the problem ? And is this problem will be fixed in the newest
2.4.22 ?

Attached the .config of the kernel. If you need more info I can try to
provide them...

OK I've just added a file called results_ksymoops.txt done with the 
command "ksymoops /var/log/messages" (I hope this is the good way to do
it)

Thanks in advance, and please CC me as I'm not on the list

Regards,

Have fun and keep up the good work you are doing ;-)

ksymoops 2.4.5 on i586 2.4.21.19062003.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21.19062003/ (default)
     -m /boot/System.map-2.4.21.19062003 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Hello all,

I've just add two hangs with a plain vanilla kernel 2.4.21 on a Debian
woody up2date. The machine is an old Pentium 100 with 64 Mb. Softs
running on this machine are :
- Apache+PHP+mod_ssl+...
- Sendmail+spamassassin
- Mailman (This can explain the python)
- proftpd
- squid

I have installed gallery for fotos and while adding many big photos at a
time  (the process is quite consuming... the CPU is 100% during this).
The problem seems to not occur when adding photo by photo

The trace on the logs :

What is the problem ? And is this problem will be fixed in the newest
2.4.22 ?

Attached the .config of the kernel. If you need more info I can try to
provide them...

Please CC me as I'm not on the list

Regards,

Have fun and keep up the good work you are doing ;-)

I said to Bernd last night I was going to run memtest over night. I
didn't think I'd find anything as the bits were brand new when I bought
them two months ago. However, memtest86 found some bad RAM around the
280MB mark and promptly locked hard just like the kernel does.

It was always the same bit stuck, a pattern ffffffff coming back as
feffffff and 00000000 coming back as 01000000. Bit unusual perhaps, a
stuck bit that inverts itself. The addresses where errors was detected
was quite symmetrical as well, ending in 3e0, 3e8, 3f0, 3f8, 400, 408,
410, 418.

I'm ordering a replacement DIMM today, and once it turns up, memtest is
seeing some action again.

2.4.21-rc7-ac1 only has the CPUFreq patches applied, courtesy of Bill
Nottingham. There is no FreeS/WAN patches applied to it.

I have just run another compile of 2.4.22-pre3, this time nothing else
applied. The oopses is as follows.

ksymoops 2.4.8 on i686 2.4.21-rc7-ac1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-rc7-ac1/ (default)
     -m /boot/System.map-2.4.21-rc7-ac1 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

If there is anything I can do to assist debugging, let me know.

Ah I misunderstood - is the 2.4.21-rc7-ac1 with or without
freeswan  patches ?

The running kernel is 2.4.21-rc7-ac1, I was trying to compile
2.4.22-pre3 with the freeswan patches applied. I can try and
compile the plain 2.4.22-pre3 a few times to provoke an oops.
The system is presently still running 2.4.21-rc7-ac1.

Will post again once I've run 3-4 compiles.

Can you replicate this without the freeswan patches out of interest ?

Hi,

Have just hit some kernel oopses again, this time when compiling the
kernel and not doing anything else. See below for details.

[1.] One line summary of the problem:

Kernel oopses when compiling new kernel.

[2.] Full description of the problem/report:

Running a compile of kernel 2.4.22-pre3 with FreeS/WAN 2.0.1 patches
applies generates oops in __free_pages_ok which in turn leads to a
completely unusable system shortly afterwards.

Only things running was Gnome 2.2, Ximian Evolution and two
gnome-terminals.

[3.] Keywords (i.e., modules, networking, kernel):

kernel, oops, gcc

[4.] Kernel version (from /proc/version):

Linux version 2.4.21-rc7-ac1 (root@tor) (gcc version 3.3 (SuSE Linux))
#2 Thu Jun 12 21:57:29 BST 2003

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)

ksymoops 2.4.8 on i686 2.4.21-rc7-ac1.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-rc7-ac1/ (default)
     -m /boot/System.map-2.4.21-rc7-ac1 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

[X.] Other notes, patches, fixes, workarounds:

This has been occuring, with or without VMware running, since I started
using kernel 2.4.21-pre/rc. It is intermittent, sometimes happening
several times per day, sometimes not for a few days.
It is hard to tell what triggers it, but it does seem to be related to
cpu usage. A heavily loaded system appears more susceptible to this
crash.



Patches gladly accepted to be tried out.

[1.] One line summary of the problem:

Unable to handle kernel NULL pointer dereference at
virtual address 00000004

Intermittent kernel oops - user programs segfaulting

[2.] Full description of the problem/report:

A previously stable system (1 year) running kernel 2.4.18 began 
segfaulting and logging kernel oops intermittently. The kernel was then 
upgraded to 2.4.20 with no change occurring. This is the only one of 
four fairly identical boxes showing the problem. The primary difference 
is that there are typically 90-100 users logging into shells via ssh. 
The problem is not reproducible. There are no load issues. The box also 
runs apache, samba and NFS. The oops are identical except for the CPU 
number.

[3.] Keywords (i.e., modules, networking, kernel):

kernel, oops, segfault, 2.4.20

[4.] Kernel version (from /proc/version):

Linux version 2.4.20 (root@earl.devnet.imsa.edu) (gcc version 2.96 
20000731 (Red Hat Linux 7.3 2.96-113)) #1 SMP Wed Mar 19 08:18:05 CST 2003

[5.] Output of Oops.. message (if applicable) with symbolic information
      resolved (see Documentation/oops-tracing.txt)

ksymoops 2.4.4 on i686 2.4.20.  Options used
      -V (default)
      -k /proc/ksyms (default)
      -l /proc/modules (default)
      -o /lib/modules/2.4.20/ (default)
      -m /boot/System.map-2.4.20 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid 
lsmod file?

   This information is of no use. Pls. read lkml FAQ, abt how to report 
oops.
   Without the symbol information the numbers won't make any sense.

   read: linux/Documentation/oops-tracing.txt
   use:   linux/scripts/ksymoops & README.

Hi, I am having problems with my kernel, it hangs up whenever I put some load 
on it (example compile GCC), I'm using kernel 2.4.19 (attached is the config 
file of the kernel) and the Oops that the kernel dump is this:

==============================================================================

I have have this very same Oops at least 10 times in the last four days, if I 
should submit more information please let me know, the odd think is that as 
long as i don't push my system, it works fine (I am writing this e-mail from 
the same linux machine)

I hope someone can help me out there

Daniel

Hello,
I have written a driver for kernel 2.2.14-5.
but some time when i try to break application through crtl-C i get kernel oops :-
because at that time machine freezes so i am not able to catch whole message waht i can read is :

Code : 89 02 85 c0 74 03 89 50 04 b8 01 00 00 00 eb 02 31 c0 c7 41
Aiee, killing interrupt handler
Kernel panic: Attempt to kill the idle task!
In interrupt handler - not syncing

But this problen is unpredictable generally it does not comes. Can any body help me in this that what could be the problem


Thanks in advance

Today I got some kernel oops again.
The output of ksymoops is attached. I am absolutely not familiar with tracing 
kernel bugs, so I hope the information below is useful for you. If not, 
please email me what to do.

My system is Debian Woody with the woodie's 2.4.18-k6 kernel as appearing in 
the log running on an AMD K6-II and 192MB RAM and 2 IDE harddisks.

Best wishes


Dirk

ksymoops 2.4.5 on i586 2.4.18-k6.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.18-k6/ (default)
     -m /boot/System.map-2.4.18-k6 (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Hello
I have a notebook running Debian (kernel 2.4) and it often hangs. I can 
reproduce kernel oops. I suspect sis900 nic driver.
I tryied kernel 2.4.17, 2.4.18 (from Debian and from Linus - vanilla and 
also patched with rpc_match module patch-o-matic netfilter), 2.4.19-pre10

Upgrade the system to a newer kernel and tools (look at ksymoops
complaining being obsolete) and try to recreate the problem.

Hi,
we are having problems with the kernel (oops). My box is a mail server only
and the problem occurs a thousand times a day . I realize a wierd message on
the boot process: /lib/modules/2.2.16/net/bsd_comp.o _> unresolved symbols,
the same message for: /lib/modules/2.2.16/misc/zft_compressor.o,
 /lib/modules/2.2.16/misc/rio.o,
/lib/modules/2.2.16/misc/dss1_divert.o.

here is my configuration:

[-- Attachment #1.1: Type: text/plain, Size: 1206 bytes --]

I've had 3 oopses in the last week that I've been playing with selinux.
ksymoops decoded results are attached. The first occurred when I was
trying to reload the policy:

Nov 21 19:33:24 bench3 kernel: ss:  loading policy configuration from /ss_policy
Nov 21 19:33:24 bench3 kernel: security:  4 users, 5 roles, 349 types

Nov 21 19:33:24 bench3 kernel: Unable to handle kernel paging request at virtual address 465ec21c

The system was still useable but attempts to reload the policy were
hanging so I rebooted.

The other two happened when nobody was doing anything with the system
except cron running the normal stuff.

Nov 22 14:40:00 tracy kernel: task_precondition:  assigning context system_u:system_r:crond_t to pid 1620 exe=/usr/sbin/crond

After this the system was hung solid, no ping or anything.

Looks like you're still using the 2.4.12-based SELinux rather than the
latest release, and it doesn't look like you've applied patches that have
been posted since that release.  Make sure that you've at least applied
these patches:

http://marc.theaimsgroup.com/?l=selinux&m=100378165408266&w=2
http://marc.theaimsgroup.com/?l=selinux&m=100445617604999&w=2

The first kernel Oops definitely looked like the load_policy bug fixed by
the second patch above.  I'm not sure about the latter two Oopses - I
haven't seen them, and they weren't in SELinux code.  Could be a side
effect of one of the two bugs for which we've posted patches.

If you upgrade to the latest release, be sure to apply the
selinux_inode_delete patch.

You can submit the message to this list, or if you use
a kernel of a distro, like RedHat, you can submit for
maintainer or support of the distro.

please, read ~linux/REPORTING-BUGS.

Hi everyone. Just a quick question: If I've had a "Kernel oops" on an 
earlier Kernel (like 2.2.19-6.2.12 on RedHat 6.2 for example), would it be 
worth reporting it to the Powers That Be, and if so, who are the Powers 
That Be and how can I contact them?

Hello,
i am recently experiencing kernel errors with httpd process,
the software used:

apache 1.3.18 running in chroot environment,
self built kernel 2.4.10,
glibc 2.2.2, gcc version 2.96, binutils 2.10)

the problem is semi-repeatable, that is it happens almost always after a few
minutes of running
that httpd, but is triggered either by running CGI scripts or trigerring
apache 40x errors.

the hardware used is P200 MMX, 64 megz of ram, tx chipset

if you need any further information i will be happy to help,

(many apologies for repost - i'll actually attach the attachment this
time)

I am running gnome netleds_applet version 0.9.1 and it is sporadically
dieing, with a various kernel oops warnings in my syslogs. I caught
the last one and ran it through ksymoops - I've attached the output of
that. It happens every few days and doesn't seem to be caused by
anything specific that I can see. Always the same program, and the
overall stability of the system seems unaffected. If it makes any
difference I have two copies of netleds running (they monitor eth0
and ppp0 separately). The processor is a Cyric 6x86MX233. Any other
information you'd find useful, please contact me!

Yes (i.e. no crashes because of this and never any X-lockup/-crash).
I'll try the non-nvidia boot and send a report to nvidia.

Only Nvidia can help you. Reproduce the problem from a boot where the nvidia
drivers have never been loaded and then its interesting. Is the box stable 
with 2.2 ?

Hi there,

when I have given my computer a 'quite heavy load' in X, it will sometimes
suddenly, without much reason at that moment itself, stop working... Ie,
the 'stop' itself can happen when the computer isn't even being worked on,
but five minutes after I've done some video editing (using a DC10+ with
Serguei Miridonov's zoran driver)...
Either I get:
- a full computer crash
- or it will segfault everything I try to do
# reboot
Segmentation fault
# ls
Segmentation fault
#
- or the kernel will oops.
Uptimes longer than a few days are usually out of the question. I've
experienced it since I switched over to kernel 2.4.x

I currently use kernel 2.4.3, on a Pentium II 400 MHz, 128 MB RAM, with
redhat 7.0. I also use the nvidia.com drivers for my videocard (tnt2),
maybe that's of importance...

the oops:

Ksymoops output when I last had the oops (only for first one, I lost the
other one):

ksymoops 2.3.4 on i686 2.4.3.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.3/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

Is blackbox broken? Or is this a kernel bug? Or a bug in the nvidia
drivers?
I hope you can fix it (if it is a kernel bug)...

* Kernel Oops

Yesterday I got an oops in a Dell PowerEdge 4100/200.
It was almost idle (the process list is listed below).
There was no SysRQ, VT, hd work, network or keyboard response.
The oops was, obviously, copied by hand; and kernel is
plain 2.4.1 compiled with egcs 2.91.66.

uname -a:
Linux sol 2.4.1 #3 SMP Wed Feb 14 18:14:33 ARST 2001 i686 unknown

Hardware:
2xiPPro 200mhz
128Mb ram
Intel eepro100
(dmesg attached)

process list:
syslogd
klogd 
httpd 
 \_ 5x httpd
crond
atd
bash 
 \_ mailsnarf 
bash
agetty
agetty
agetty
bash
 \_ vmstat 1
inetd

Attached are the plain oops, the oops passed through ksymoops, the dmesg
output and the kernel config.

Thanks,
        Alberto

OK, I even found out the code to make it crash. It definitely _is_ the
driver. I stop disturbing you with that and send it to the kernel ML.

Sorry for the bandwidth

I've been working on getting the DoC driver to work when compiled
statically, and have managed to get past all the gotchas with respect to
compiling, but now I get a kernel oops on boot.  I've looked into it a
bit, but since I'm not the greatest decoder of oops messages the world has
ever seen, I haven't found the problem.  I've attached the ksymoops-ified
oops message in case anyone is a wizard with these things. :-)

I'll start tracking it down with printk (my read of the oops is that it's
happening somewhere near the beginning of DoC2k_init).
