Subject: 2.6 kernel won't reboot on AMD system

Before you hit 'reply', no, I'm not talking about the machine not 
getting past the BIOS check complaining that there is no keyboard present.

Kernel 2.6.7

model name      : AMD Athlon(tm) XP 2400+

motherboard: http://www.ecsusa.com/products/km400-m2.html

... not sure what else might be useful... apci=off added to boot 
options.  Preemptive kernel.

In any case, the machine in question does not reboot.  I traced the 
problem down to the mach_reboot but it doesn't get past those assembly 
instructions.  Things do seem to work alright if a keyboard is 
installed.  Otherwise, the machine just sits there, no longer responsive 
to pings or anything else.

This appears to be a somewhat common problem, as I found several other 
posters discussing it:

http://marc.theaimsgroup.com/?l=linux-kernel&m=108868695814658&w=2

any ideas on what parts of the kernel to look at in order to determine 
what is causing this?

Thankyou,
