Hi Matthew,
Could you please perform the following testing:
1. boot, make sure the fan doesn't spin.
2. do 'cat /proc/acpi/thermal/*/*', check the following:
- the 'state' field shows 'active[<smthng>]'
(if not - perform some CPU-intensive task);
- fan still doesn't spin,
3. do 'cat /proc/acpi/fan/*/state', check the following:
- the 'status' field shows 'on' (at least one of them);
- fan still doesn't spin,
4a. do consequently (as root) the following:
- 'echo 3 > /proc/acpi/fan/*/state'
- 'echo 0 > /proc/acpi/fan/*/state'
(the fan should be that one, which shown 'on' in step 3)
4b. (if step 3 failed) do (as root) 'echo 0 > /proc/acpi/fan/*/state'
consequently for each fan device under /proc/acpi/fan/, check the
following:
- fans start spinning;
- fans' states are correct ('cat /proc/acpi/fan/*/state'
command)
5. check if the fan(s) start spinning.
Please, get back to me with the results, test flow description and
commands' outputs.
Also, you could try the patches from bugs ##7122, 7570 for 2.6.20-rc3 to
see if it help.
Regards.
Konstantin.
