5.0.1 : acerhdf - Acer Aspire One Fan driver
« on: October 05, 2013, 06:38:18 AM »
Hi everybody,

I just went from CorePlus 4.2 to 5.0.1 (new install).
Everything works fine except acerhdf:

modprobe acerhdf fanon=58000 fanoff=5200 returns no error messages and
dmesg shows:
   acerhdf: Acer Aspire One Fan driver, v.0.5.26
   acerhdf: Fan control off, to enable do:
   acerhdf: echo -n "enabled" > /sys/class/thermal/thermal_zone0/mode
   acerhdf: kernel mode fan control ON


next I do:
echo -n "enabled" > /sys/class/thermal/thermal_zone0/mode


cat /sys/class/thermal/thermal_zone0/mode reports:
   enabled

all of this looks very good, but:

cat /sys/class/thermal/thermal_zone0/temp reports:
   46000

so the fan should be of, but it is still purring along happily (and noisily).

Any ideas?

Cheers,
   Raschid
