[Intel-gfx] intel_crtc_wait_for_pending_flips

[Kenneth Johansson]

I have a rather infrequent hang of the graphics system but when it 
happens the only way out is to pull the power. This has happened on 
serveral kernel versions but it is infrequent enough so that I now only 
have the most resent still in the logs.

what I remember is that I always see intel_crtc_wait_for_pending_flips 
on the call stack.


here is the tracebacks that I have in the log. I had to pull the power 
since I could not switch to a VT from X and I could not get it to do a 
reboot.
