Hi

Please go to the BIOS, Intel Advanced Menu -> Power and Performance -> CPU
Power Management Control -> Package C state Limit, then set it to "C10".

Then test this tree:
http://cgit.freedesktop.org/~pzanoni/linux/log/?h=bdw-pc8-fixes . Don't forget
to switch to the bdw-pc8-fixes branch.

Please also boot with drm.debug=0xe and send the dmesg output in case there's
any problem.

Thanks,
Paulo
