Hi,
As a new version of thinkfan appeared, I tried some new tests; no
change, the problem remains. After a suspend/wake up, I see:
> Jun 7 12:16:42 Wintermute thinkfan: /proc/acpi/ibm/thermal: No such
file or directory
> Jun 7 12:16:47 Wintermute thinkfan: Cleaning up and resetting fan
control.
Note the difference in the times: the missing file in /proc is reported
during the suspend process, not during the wake up. I think that the
entry is removed during the suspend process (don't know exactly what is
performed there), which thinkfan realize when its periodic sensor
polling (i.e. trying to read the temperature from the then missing
/proc/acpi/ibm/thermal), which causes it to die.
Surprisingly, the problem does not disappear whith the -D flag (neither
with the -z "Assume we don't have to worry about resuming from standby
when using the sysfs interface"... that I actually tried before
realizing that the problem is in /proc and not /sys). So disabling the
"sanity check" does not prevent thinfan to die when the sensor are not
detected (even if temporarily).
The only (weak...) workaround that I have is a "0 * * * *
/usr/sbin/service thinkfan start" in my crontab, so that my laptop stays
at most on hour without thinkfan running.
Thank you,
Raphaël
