[Bug 1047476] [NEW] Entering suspend sometimes causes fans to go full speed

Public bug reported:

Upon entering suspend mode, sometimes the fan will go full speed.  It
could be the case fan, or the CPU fan.  It happens about half the time.
The fan will remain at full speed while in suspend until the system is
resumed and then it will work normally.

Fan speed is controlled by the BIOS.  My motherboard is an Intel DH77DF.
