From your provided result all cooling fans are supposed to be turning at 66 (kernel 3.2.10 ) and 72 (kernel 3.3.3) degree C. By fact of examining these values ..
/sys/class/thermal/cooling_device[0-9]/type is "fan" and /sys/class/thermal/cooling_device[0-9]/sys/class/thermal/cooling_device[0-9]/cur_state is "1". My idea is basically like this If there's any fan not turning .. there seems to be wrong in firmware(as it reports turning but actually not ..). If all fans did work, try to reproduce your problem and find any corresponding cooling_device node (/sys/class/thermal/cooling_device?) that cur_state is "0" and type is "fan" and see what temperature in trip_point it was associated with (the output of comment #14 would be helpful to identify it). In theory, the thermal_zone?/temp should be lower than that trip_point temperature. If you interested in explaining the thermal sysfs it's in the kernel documentation. http://www.mjmwired.net/kernel/Documentation/thermal/sysfs-api.txt Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
