>Description:
Tyan Tiger100's APM-BIOS does not work and return immediately if called
from CPU#1. If called from CPU#0, it works.
So, 'shutdown -p' does not work.
>How-To-Repeat:
'shutdown -p' on Dual-Processor Tyan Tiger100
>Fix:
Here is a patch for /sys/i386/apm/apm.c
I know that synchronize by smp_rendezvous() is not so good
but it's for power-off...
