Description Chow Loong Jin 2011-06-23 14:54:23 UTC
Eventhough I can hear the fan running, every userspace interface I have poked seems to say it's at 0RPM.

/proc/acpi/ibm:
status:         disabled
speed:          0
level:          0

This is true also for Thinkpad edge 530. They changed once again the EC config it seems. This bug is likely a dup of bug #43048 

If someone want a tester or would just mind to explain me the basis of this stuff so I can just write it myself, make a whistle.
