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 sascha [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. -- Sascha Wilde If you think technology can solve your problems you don't understand technology and you don't understand your problems.
