Description jouni 2001-10-27 17:26:36 EDT

Description of problem:
I tried first time to make power off to work on my SMP machine (ASUS
P3C-D, Dual PIII 750MHz, 512 MB RDRAM).  I added apm=power-off to 
grup.conf.
When I try to boot the kernel freezes totally after following lines on 
terminal:

    apm: BIOS version 1.2 Flags 0x03 (Driver version 1.14)
    apm: disabled -APM is not SMP safe (power off active).

This happens both with original and errata 2.4.9 kernel.


Another problem:

When I booted my box after the frozed boot-up, the fsck was the same slow 
check during next boot as with ext2.  (Just double-checked /proc/mounts:  
all ext3.)

Only non-standard procedure during boot was editing the boot command 
inside grub to boot without the apm=...

Best regards,

Jouni

This looks like your bios is totally broken in this respect ;(

This is not that uncommon, and is the reason poweroff is disabled by default on
smp....
