i915_error_state after the hung messages

When resuming a hibernated Linux 3.8 (suspend-to-disk), I get the following
errors in dmesg:

[133824.298846] Restarting tasks ... done.
[133824.302138] video LNXVIDEO:00: Restoring backlight state

Similar hung messages are to be found in Xorg.0.log, but I failed to capture it
before rebooting.

This is a regression from 3.7. With the exact same userspace, resume-from-disk
works on all 3.7 kernels I've tried, and it fails on all 3.8 kernels I've
tried.

Steps to reproduce:
1) suspend-to-disk
2) resume-from-disk

I initially thought this was related to suspend-to-disk while an extra output
was enabled, besides LVDS, and resuming while that output was not connected.
That particular bug happened in 3.5 or 3.6, but disappeared in 3.7.
