Public bug reported:

Binary package hint: linux-image-2.6.31-14-generic

When entring suspend mode the kernel prints a warning in dmesg and after resume 
the fan goes at maximum speed and never slows down. If the system is suspended 
a second time the fan goes at minimum speed and doesn't speed up at all.
This behaviour repeats always and rhe only way to get things right is to reboot 
the machine.
