Lenovo resume from suspends hangs in i915_gpu_busy or so

[Norbert Preining]

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 (
Stack:
  
   
  ...
Call Trace:
  
  ... ? tick_program_event
  call_sortirq
  do_softirq
  irq_exit
  smp_apic_timer_interrupt
  apic_timer_interrupt
  
  ? _raw_spin_lock
  i915_gpu_busy
  ips_adjust
  ? show_cpu_temp
  kthread
  kernel_thread_helper
  ? kthread_worker_fn
  ? gs_change
Code: ...
(once more more or less the same as above)

Here the original message.

Hm, ok so on resume we're checking GPU busyness, which is normal, but
end up hanging on the spinlock?  Do you see what scrolls by above the
text you took a picture of (probably a "task hung" message?).

Does this happen reliably?  Does a previous kernel work ok?
