Hi *,

same problem here on my HP Compaq 6910p.

I just tested with vanilla linux 3.8.2 -- unfortunately the problem
still persists.[1][2]  The last (stable) kernel working for me is 3.6.11.

I'll happily provide any additional information which might help getting
this fixed.  Just ask... :)

Please CC me in any response, for I'm not subscribed to lkml.

cheers

[1]  FWIW, self build vanilla linux 3.8.2 with very generic config on
     Debian Wheezy 64bit.
[2]  FWIW², I'm under the stron impression that the whole fan control
     changed in the latest vanilla kernels on my 6910p even before doing
     a suspend/resume -- it seems to be more "binary" if you will, in
     that the fan is not running at all for a while and then at a 100%
     to return back to 0% after doing some serious cooling.  With 3.6.11
     and older it is more "analogue", with slow fan when only a bit
     cooling is needed.  No idea if this is related to the issue at
     hand.
