Public bug reported:

Binary package hint: acpi

hello i am having a problem with my fan not starting when i start my
computer off a clean boot. the fan starts up in bios and in boot menu
but once ubuntu 9.10  starts it kills the fan.  the tempature starts
increasing a lot till it eventually kills the pc and shuts it down. once
powered on again it starts the fan back up but same problem happens when
starting ubuntu.

though i have found that it works when starting from a hibernate status
(which never used to happen with acer aspire series). this is the only
way i know how to get around this problem.

this problem happened after upgrading from jaunty to karmic.
the fan works in windows, bios, and grub. 

i have tried 3 kernals and problem exists in all of them. 
2.6.31-16
2.6.31-15
2.6.31-14
specs:
pc: aspire 5315
1.5 gb ram
celeron 2.0 ghz  550
gnome 2.28.1
