If I do a dmesg, I get line after line of "[drm:__gen6_gt_force_wake_mt_get] *ERROR* Timed out waiting for forcewake old ack to clear". Literally there are loads of them!
If I go into TTY2 using Ctrl Alt F2, they continuously appear there too and keep generating every few seconds - the same error.
What could it be?

I had the same problem. Reverting commit 36ec8f8774 (drm/i915: unconditionally use mt forcewake on hsw/ivb) solved the problem for me. This is for IvyBridge CPUs only.
Thanks, groeck. Mine is also Ivy Bridge. Would you know how I can "revert the commit" too please?
I would like to apply this patch but I'm not sure how to.
Can anyone help please?
Problem solved after today's kernal update.
