Hello everyone.

I haven't tested fresh 3.8.x kernels lately because there is also another bug
that's really annoying and I was running 3.7.10, but I've finally decided to
give 3.8.4 a try.
Surprisingly, this bug is there.

After a little investigation I found out that at some point patch named:
"drm/i915: enable irqs earlier when resuming" was introduced to 3.8 branch and
this is merely the patch attached above, but recently revert of this patch was
also merged into 3.8 branch AND is included in 3.8.4. That's why this bug is
resurfaced again.

The commit message of revert says: "It caused problems in the 3.8-stable
series, but 3.9-rc is just fine." So, this revert breaking things again on
3.8.4 kernel and doesn't belong to 3.8 branch as stated in commit message.

Please revert this revert, i.e. leave the changes made with the patch
"drm/i915: enable irqs earlier when resuming".
