2.2.22 on HP Vectra 90/5: Machine check exception on boot

2.2.22 on HP Vectra 90/5: Machine check exception on boot

[Ville Herva]

[-- Attachment #1: Type: text/plain, Size: 393 bytes --]

Trying to boot 2.2.22 on HP Vectra 90/5 gives and endless stream of these:

CPU0 Machine check exception 0x  10E2C0 (type 0x    09)

2.0.35 does boot just fine.

If I optimize for i386 instead of Pentium, I get a different MCE, but it
doesn't boot.

Compiled with
kgcc --version 
egcs-2.91.66

The /proc/pci, dmesg output from 2.0.35 boot are attached as is the .config.

(It's actually Vectra XU 5/90, not 90/5 - now that I have physical access to
the box again. The google is full of horror stories about problems with this
particular model ;).

I tried SMP kernel, and it went a little further (no MCE) but it halted
after "Intel old style machine check architecture supported". For some odd
reason, linux says the box has 2 cpu's during boot, but it afaik only has
one.

The I forced mce_disabled to 1 in bluesmoke.c, and the SMP kernel booted.
During init, it oopsed, however.

I then compiled an UP kernel again, with mce_disabled=1 (same as "nomce" I
gather), and it booted.

The 3c509 appears not to work (but was found), scsi cdrom coughs badly but
it did boot :).

Thanks.

Serious Problems with diskless clients

[Marco Schwarz]

Hi all,

my diskless clients have some severe problems on one of my servers.
Sometimes (right now most of the time) everything just hangs at the same place when
starting up the kernel. Here are the last messages I get (right before this
IP-Config is running and looks OK):

NET4: Unix domain sockets 1.0/SMP for Linux NET4.0

Looking up port of RPC 100003/2 on 192.168.0.235

Root-NFS: Server returned error -5 while mounting /netclients/192.168.0.87
VFS: Unable to mount root fs via NFS, trying floppy
VFS: Insert root floppy and press ENTER

I am thinking right now that we have some problems with network hardware,
but maybe its a Software problem. Could someone tell me what the 'Looking up
port of RPC 100003/2 on 192.168.0.235' in kernel startup is doing an why it
could fail ?

We have Kernel 2.4.10 on both server and clients (I also tried 2.4.19, but
it changed nothing).

Thanks,
Marco Schwarz

I have 2 diskless machines both tftping the kernel from the network and they
work just fine.  Both are using kernel 2.4.19 vanalla with a small patch to
force ip=auto if nfs=/dev/nfs

[wakko@gohan:/] uname -a
Linux gohan 2.4.19 #1 SMP Tue Sep 3 13:02:36 EDT 2002 i686 unknown

/proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
[wakko@gohan:/] 

It's a very small patch to make that work w/o saying ip=auto on the command
line (I did this originally because I used a kernel disk w/o a boot loader
on some boxes at work)

I did a cut'n'paste so I don't know if it will apply correctly but you get
the idea.

One thing I had problems with was using USB to mount the rootfs (usb hdd
actually) and I suspect the same with a USB nic (loading the kernel from
floppy).

"mot responding" is just a typo, I had to type all the messages from screen
;-)

I already tried pinging, works in both directions. On the server I start
portmap now with 'portmap -v' and I am able to see the requests from the client:


'connect from 192.168.0.87 to getport(nsf)'
'connect from 192.168.0.87 to getport(mountd)'

I also see some messages from Portmap which look like this:

'connect from 192.168.0.87 to dump()'

I also have to note that I have 2 NICs in this server, one with adress
153.95.240.x and one with 192.168.0.x.

Problems seem to occur only on the 192.168.0.x network (I already
interchanged adresses between cards, no effect).

BTW: Is there a newer version of portmap than 5.1 ? I wonder if this is
maybe related to portmap ...

Regards,
Marco

Hook another box to the same network segment and run
ping or mtr to 192.168.0.235 and to the booting box.
Maybe your net drops packets or otherwise misbehaves.

BTW, 2.4.10 is way too old. 
I don't see "mot responding, timed out !" in 2.4.19
source, rather "not responding, timed out".

This together with the nfs-root-path-patch would be a nice addition to
the kernels I think, I find myself forgetting to add a few options every
now and then which is really nasty time-wise.
