Re: [opensuse] openSUSE 11.0 on Dell Precision 490: Reboot problems

Hi,

We noticed that some of our Dell Precision 490 workstations do not power
cycle with openSUSE 11.0. When typing "reboot" it halts but does not
poweroff or reboot. One has to manually press the power button.

The 490 workstations had BIOS A06 installed, but an update to A08 did
not help. Other 490 workstations that worked fine previously had BIOS A00.

We're preparing a migration from Suse 10.1 to openSUSE 11.0 and during
the Autyast installation the system should boot 4 times.

Are there any known issues about this or does someone have have a clue?
I didn't find something in the BIOS settings.

Bye

Not being familiar with that machine, I assume its a dual processor
(or core 2)?

This does happen in dual processor machines (has happened for a long
time) because one processor can't be sure the other processor is
done.

ACPI was supposed to fix this, but I've seen this in certain rare
occasions on modern core 2 machines. Also seen it under ubuntu.

The boot command line parameter "acpi=force" might work. Seems
to work with ubuntu.

You might also check that the machines have the latest bios.
