Hi, Roberto,

please attach the acpidump output.

Hello,
with recent kernels after a suspend/resume cycle on my laptop (HP
6730b) the fans stays at full speed.

does the fan keep running at full speed after resume?

yes, the fan never stops and runs always at full speed.

please attach the output of "grep . /sys/class/thermal/*/*" before
suspend and when the fan is running at full speed.
please attach the same stuff in a good kernel.

See attached files.
3.6.9 is the good kernel where the fan behaves correctly.
3.7.0+git is the bad one.

Kind regards
R

thanks,

I've bisected down to this commit:

ce119f83257aae29b84a5bfad0669e8348437b18 is the first bad commit

Thermal: Introduce simple arbitrator for setting device cooling state

This fixes the problem that a cooling device may be referenced by
by multiple trip points in multiple thermal zones.

With this patch, we have two stages for updating a thermal zone,
1. check if a thermal_instance needs to be updated or not
2. update the cooling device, based on the target cooling state
of all its instances.

Note that, currently, the cooling device is set to the deepest
cooling state required.

I tried to revert it but there are rejects so I cold not try current
kernel with simply this commit removed.

As a side note when the fan is at full speed a see an anomaly on thermal
indicator #4

$ grep 0 /sys/devices/virtual/thermal/thermal_zone*/temp

while the others seem to report normal value. Attached the output of
dmesg on this laptop.

More info/testing on request.
