Hey Adrian,

issues with AOA 150 netbooks should be solved with current 2.6.32-git tree. You can also try to use latest acerhdf of http://piie.net

kind regards,

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
