It always worked for me, but then again, I don't have your hardware.
Could you find out which was the first update kernel for SUSE Linux 10.0
that couldn't poweroff your hardware anymore? This would make it easier
to find the problem.
Sorry this took some time. But I've had serious trouble getting 10.1
beta2 properly installed. I've tried both upgrades from 10.0 and new
installations several times, and most of the times 10.1 hangs somewhere
during the installation or during boot up. When it installed one time
and I was able to login, there was almost no response. The system worked
useless sluggish trying to start any application.
Therefore I had to drop the 10.1 beta2, go back and reinstall 10.0 from
scratch again from the initial CDs, and next run Online update.
Once you know the last working and the first non-working kernel, boot
the last working kernel and after boot run
# dmesg >dm1
The initial x86 kernel that worked with regards to power off was version
2.6.13-15-default.
The file /boot/grub/menu.lst didn't yet contain any "acpi" or
"acpi=force" parameter
Then boot the first non-working kernel and run
# dmesg >dm2
The Online update kernel where Power Off was gone is version
2.6.13-15.8-default
# diff -u dm1 dm2
That diff will probably show the reason for the poweroff failure.
I noticed especially the following ACPI lines in the boot messages from
the last kernel 2.6.13-15.8-default
ACPI: BIOS age (2000) fails cutoff (2001), acpi=force is required to
enable ACPI
ACPI: Disabling ACPI support
Side note: Could you add acpi=force to your kernel parameters? I have
a strong suspicion that this will fix it.
I added "acpi=force" into the file /boot/grub/menu.lst and then Power
Off worked again.
The question is lastly, why this change was introduced in the 10.0
kernel update and also in 10.1 beta2? As I wrote above, acpi=force
wasn't necessary for the 2.6.13-15-default kernel.
Thanks for the tip,
