Subject: Lenovo resume from suspends hangs in i915_gpu_busy or so

Hi all,

adding dri-devel as I found it is actually not completely dead, 
but hanging in some i915 problem.

Copyied from screen:
Process ips-adjust (....
Call Trace:
  ... ? tick_program_event
  ? _raw_spin_lock
  ? show_cpu_temp
  ? kthread_worker_fn
  ? gs_change
Code: ...
(once more more or less the same as above)

Here the original message.
