Output from 'ls -R /sys/class/thermal' 

In kernel 2.6.38, the cpu fan runs at its full speed. I have HP Compaq 6715s
with the cpu Mobile Sempron 3400+. 2.6.37 was ok (but it had another problem.)

Attached is the output from ls -R /sys/class/thermal. The result is the same
as previous kernel versions.

Changes I've noticed are:
* thermal/{cooling_device,thermal_zone}?/power has new entries
autosuspend_delay_ms, wakeup_active{,_count},
wakeup_{hit_count,last_time_ms,max_time_ms,total_time_ms}
* In 'flag' field of cat /proc/cpuinfo, 'nopl' is added.

Rafael Wysocki said to come here. Thank you very much in advance.
