Kernel panic...

[neel vanan]

Hi,
currently i am compiling kernel 2.6.0-test11, After
making kernel image and installing new module when i
boot with new kernel image i am getting this error:

Could you post your .config?

Okay, the first thing to try is removing devfs from the equation if
possible. Your mount is getting back -ENXIO, suggesting whatever device
you're trying to mount doesn't exist according to the kernel. devfs
does device management internally to the kernel, so it's a likely culprit.

It would also be helpful to find the command-line arguments issued to
mount(8) when it's failing, as well as more information about the
contents of your initrd. Can you boot without an initrd?

acpi related error.....

[neel vanan]

Hi list,
Currently i am working on RedHat9.0 kernel 2.4.20-8, i
am compiling kernel 2.6.0-test11 with NUMA and SMP
enabled. I had selected summit though i am having
non-summit box. When i am trying to make bzImage in
the last i get this message:

How can i compile this without commenting these lines.

Thanks.

You are likely enabling CONFIG_NUMA on a PC subarch or trying to build
CONFIG_X86_SUMMIT without CONFIG_ACPI; this is ridiculous as PC means
non-NUMA and Summit means ACPI. I'm not sure how you selected this
combination.

Best to turn off CONFIG_NUMA unless you have an x440, x445, or NUMA-Q.

Kernel panic.. in 3.0 Enterprise Linux

[neel vanan]

Hi all,

The kernel I have working is version 2.4.21-4.EL and I
can still boot up to that. I compiled a 2.6.0 version
and installed it in exactly the same way that the old
version is, just appending 2.6.0 to the end of the
file. so when I reboot I get a boot screen that shows:

Red Hat Enterprise Linux AS (2.4.21-4.ELsmp)
Red Hat Enterprise Linux As-up (2.4.21-4.EL)
Red Hat linux (2.6.0)

Enterprise linux still boots up fine but when I try
and boot up Red Hat linux (2.6.0) I get some ouput and
then a kernel panic with this message:

<snip>
Software Suspend has malfunctioning SMP support.
Disabled :(
ACPI: (supports S0 S1 S4 S5)
RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-1 !=32768) 4194304
VFS cannot open root device "LABEL=/" or unknown block
(0,0)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on
unknown-block(0,0)

I am running Linux Enterprise Edition version 3.0 on
my server. It has 2 Xeon processors and 1 U360 scsi
HD. The whole reason behind my compiling a kernel is
trying to get support for high memory (this 
machine has 4 gigs of ram) and multi-processor
support.

I'm pretty sure I selected all scsi and driver support
because when i run the same kernel with RedHat Linux
9.0 in same machine it works fine. Everything is
compiled in and not as modules.

This is snip of my grub.conf file:
# grub.conf generated by anaconda
#
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm
title RedHat Enterprise Linux AS (2.4.21-4.ELsmp)
	root (hd0,0)
	kernel /vmlinuz-2.4.21-4.EL ro root=LABEL=/
	initrd /initrd-2.4.21-4.EL.img
title RedHat Linux (2.6.0)
	root (hd0,0)
	kernel /linux-2.6.0 ro root=LABEL=/
	initrd /initrd-2.6.0.img

Any help would be greatly appreciated! Thanks in
advance,

Neel

LABEL= is a RedHat extension. Please use the normal root options that is
described in the Grub or kernel documentation.

[Andreas Unterkircher]

have you rebuild your initrd? you have written you
have compile in all needed things - so do you still
need the initrd? if not - try to remove the line...

It's not even a Red Hat extension.  The LABEL= stuff is
done entirely in userspace, on the initrd.

If you do not want to use an initrd, you need to use the
normal root options instead, something like root=/dev/hda3

RHEL3 isn't quite 2.6 ready btw; you need to update quite a few packages
to get it working right.

Also if you use mount-by-label you do need to create an initrd (with a
2.6 capable mkinitrd)...

I was misinformed then. Thanks.

His initrd can't be correctly loaded. It seems the initrd is larger than
4MiB but he didn't increase the maximum size in the kernel
configuration.

could you please summarize which ones? i upgraded modutils and modified
rc.sysinit for usb support. the rest works unmodified (except NVIDIA
proprietary kernel driver which does not have 2.6.x support yet, but XFree86
driver works fine for me) as far as i can tell. i got exactly 0 (zero)
kernel panics up to now. compared with 2.4.0 few years ago, 2.6.0 works
like charm

2.6.0 works with 3.0 Enterprise Linux or not...

[neel vanan]

Hi All,
I had posted my problem in mailing list i didn't get
proper response.
I would like to know whether 2.6.0 works properly with
Enterprise Linux 3.0 or or not. For me it works fine
with RedHat Linux9.0 but same kernel didn't boot with
EL 3.0. Arjan had replied that i have to upgrade some
packages but how many that is mystery. If i have to
upgrade than how many packages i should upgrade. I
have already upgraded mkinitrd and modutils still it
gives this error while booting:

Software Suspend has malfunctioning SMP support.
Disabled :(
ACPI: (supports S0 S1 S4 S5)
RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-1 !=32768) 4194304
VFS cannot open root device "LABEL=/" or unknown block
(0,0)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on
unknown-block(0,0)

I had also tried root=/dev/sda2 and also root=0802.
But still it is not booting.

Help needed urgently, Thanks in advance.

Neel.
