Heyho!
With 2.6.31 (as packaged by Debian), kernel and BIOS are still fighting over
who controls the fan on my Acer AOA-150.
If the system is idle, I see repeated
Nov 20 08:07:12 laeggerli kernel: [100246.224141] acerhdf: temp 51
Nov 20 08:07:12 laeggerli kernel: [100246.272136] acerhdf: fan OFF
Nov 20 08:07:22 laeggerli kernel: [100256.328145] acerhdf: temp 51
Nov 20 08:07:22 laeggerli kernel: [100256.376072] acerhdf: fan OFF
(and the fan is turned on and off accordingly, using a rather noisy speed
for ca. .5s every time.)
As soon as the system gets a bit warmer, fan is running on low speed and the
system is much quieter.
ISTR reading that this should have been fixed in 2.6.31, or was that wrong?
Did anything change in current kernels or the separate releases of the
acerhdf driver? I might be able to run newer driver releases, or at least I
can provide more info if desired (and if you're patient to deal with quite
slow round trip times from my side. It's not an urgent problem either.)
cheers
