Hi Matthew,
Could you please perform the following testing:
Well , i tried to perform this steps in my machine since i think my
fans are not working in linux. Well , for my surprise , i have
absolutely nothing in
# ls -lh /proc/acpi/fan/
total 0
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,
#cat /proc/acpi/thermal/*/*
cat: /proc/acpi/thermal/*/*: No such file or directory
#cat /proc/acpi/thermal_zone/*/*
<setting not supported>
cooling mode: critical
<polling disabled>
state: ok
temperature: 60 C
critical (S5): 99 C
<setting not supported>
cooling mode: critical
<polling disabled>
state: ok
temperature: 27 C
critical (S5): 105 C
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,
# cat /proc/acpi/fan/*/state
cat: /proc/acpi/fan/*/state: No such file or directory
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.
any ideas why i have no /proc/acpi/fan/*?
