Title:
  [Asus A8JP] Fan speed control is frozen

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Behaviour:

  The fan speed remains on the same level after the kernel was booted.
  That means that the fan is still off when the Laptop is booted with
  cold hardware, the fan remains off, leading to an emergency shut down
  at100°C.

  If the system is booted when still hot, the fan is turned on at
  maximum speed. The fan stays at this speed, even when the system has
  cooled down.

  This problem did not happen before upgrading from 13.10 to 14.04.

  When I boot an old installed kernel (3.5.0-44-generic), the problem
  does not occur.

  Expected Behaviour:
  Fanspeed is selected to actual temperature of the system
