Kernel panics on Asrock K7VT2.

[Adam Funk]

I installed Ubuntu 7.10 to try out the LVM-crypto stuff on an old
computer with (according to lshw) an ASRock K7VT2 motherboard, Athlon
XP 1800+ processor and 255MB of RAM.  I carried out the upgrades and
it's now running (according to dmesg) "Linux version 2.6.22-14-generic
(buildd at terranova) (gcc version 4.1.3 20070929 (prerelease) (Ubuntu
4.1.2-16ubuntu2)) #1 SMP Fri Feb 1 04:59:50 UTC 2008".

The installation seemed to be fine, and the computer boots up without
any apparent problems, but generally dies mysteriously within 2 to 120
minutes.

Symptoms: the gdm login screen freezes, and sometimes the caps lock
and scroll lock lights blink.  Not very informative, so I left it on a
virtual console and found the following at the end of the error
output:

EIP: [<c02f3f91>] _spin_lock+0x1/0x10 SS:ESP 0068 c3867eb4
Kernel panic - not syncing: Fatal exception in interrupt


I've tried booting with "acpi=off", "noapic" and both options.

I'd be grateful for any further suggestions for getting it to stay
running!

Thanks,
Adam
