Linux 2.2.0-pre4 crashes on poweroff. The oops message is many pages long

You are the second person with a Gigabyte motherboard to report this.
We suspect a bad BIOS as the line
> EIP: 0050:[<00008896>]
indicates that the code is being executed out of the BIOS (no the
Linux kernel). The 0050 is the APM BIOS's 16 bit code segment. Does
this also crash with previous kernels?
Cheers,
Stephen

I've noticed the same behavior, on a HP vectra (using HP's BIOS), on a
SuperMicro P6-DS (Modern AMI BIOS) and on an ASUS P2B-DS (Award BIOS). It's
also interesting to note that if the LK is compiled UP, APM is enabled, and
the config ooption for "poweroff on shutdown" enabled, the machine/BIOS powers
off just fine. So perhaps what's happening is that the kernel's SysRq
poweroff feature isn't initializing the APM the way it would otherwise have
been initialized, and this is causing the BIOS to become confused.

So are you implying that all the faulting machines are SMP?

No, as the Vectras are both UP, but I couldn't rule it out either; I haven't tried
to poweroff via the kernel on one of the Vectras in a long time, so memory fades
there. But yes, it's possible it's SMP related, as the SMP kernels don't go to the
bother of initializing APM upon bootup.

It crashes with 2.0.35, 2.0.36, 2.1.115. One of the 2.0.36 pre
patches worked fine, though. I just don't remember which one.

Throw in a me, too here.

Hmmm. I've been trying to get this to happen myself, but I can't. I have
all of those options compiled in, and I'm using the latest sysvinit, but
/sbin/poweroff just halts the machine. I'm using an AOpen AX59Pro (VIA
MPV3) BIOS v1.1. Can anyone help me (off the list, unless there's a quick
answer)?
Thanks,
Danek
