Description of problem:
After updating the kernel from 2.4.7-10 to 2.4.9-13, I get a kernel panic
when running shutdown -h. The panic occurs right at the end of the shutdown
cycle while running "halt" (after unmounting files). This is on an AMD
K6-2/350 machine, VIA MVP3 chipset. The board is an AT board with AT power
supply, hence, there is no possibility ofatuomatically shutting the machine
down via software. I tried different BIOS APM/PM settings as well with no
difference. I had no such problems with kernel-2.4.7-10.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.as root, run "shutdown -h now"
2.at end of shutdown,kernel panics
Expected Results: Message "Power down." as with kernel-2.4.7-10

It's possible to avoid the kernel panic by recompiling the kernel with APM/PM
disabled, as I just found out. However, due to the time it takes to do so,
having an RPM for non-APM kernel might be an idea.
Can you try passing "apm=realmode-power-off" as kernel commandline argument ?
That changes the way a poweroff is tried.
Also, if that doesn't work,
"apm=off" will disable apm
(both can be added to the /boot/grub/grub.conf file to the line with vmlinuz in it)
