Hi

Can you please apply "[PATCH 1/6] drm/i915: don't schedule force_wake_timer at
gen6_read" from the mailing list and test the tree again? It fixes the problem
on my machine.

Here's the link to the patch: http://patchwork.freedesktop.org/patch/21687/

If that fixes your problem, we can mark this bug as a duplicate of #76544.

Thanks,
Paulo
