Public bug reported:
I'm using a new intel processor i7 and DZ77BH-55K motherboard.
Right after turning my computer on, my two fans run pretty quietly. Here is the
sensors output:

But after suspending and waking up the computer, they accelerate and
become quite noisy. The sensors again:

As you can see, the temperature is still low enouth, but the friquency
of fans almost twoced. I ran pwmconfig to controll them manually, but,
although, it detected them, it wasn't able to stop each one of them.
I suspect it is a kernel, so here is my uname -a:
Linux bragaton 3.2.0-32-generic-pae #51-Ubuntu SMP Wed Sep 26 21:54:23
UTC 2012 i686 i686 i386 GNU/Linux
Expected:
pwmconfig stops any fan.
Happend instead:
pwmconfig unable to stop any fan.
I attached the full log of pwmconfig session.
