Public bug reported:

After resuming from RAM and sometimes after rebooting, fan control
appears to be inactive, resulting in no fan activity at all until at
85°C the fan kicks in at full speed for a short time, only to cease all
activity again until the temperature reaches 85°C again.

This started occurring after upgrading from Ubuntu 13.10 to 14.04 LTS.

I have regrettably already removed older kernel versions, so I am not able to verify that the problem does not occur with them.
MainlineBuilds will be tested and results posted shortly.

I am currently partially circumventing the problem by having 
*/2 *    * * * echo 1 | tee /sys/class/thermal/cooling_device[0-4]/cur_state >/dev/null 2>&1
added to crontab -e.
