------- Comment #12 from bernhard.bender@xxxxxx 2007-02-12 17:14 MST -------
Okay, in addition to the patches mentioned in comment 8 I have applied the
following:

acpi-suspend-resume.patch
move_GPEs_disabling_to_sleep_prepare.patch
call_acpi_sleep_init_from_acpi_init.patch
pm-change-suspend-to-RAM-ordering.patch

However, nothing has changed.
ACPI still seem to be unable to turn fan level on.
It does turn the off during boot when the machine is still cold. But the do not
come on again once they have been turned off.

If I reboot the machine when it is already warm, fans remain on, but turn off
after some time...

When I run a heave workload on the machine (e.g. linux kernel build)
temperature rises to >80 C, then some kind of emergency device turns on the fan
full power until it cools down again to ~70 C. At the same time, fans remain
off in there /proc/acpi/fan/*/state.
