[snb mesa mir] GPU lockup IPEHR: 0x7a000003

[Curtis Hovey]

The screen, keyboard, and pointer locked up while viewing google maps in chromium. I was dragging the map. This is the first lockup I have experienced with xmir[1]. After 10 minutes of lock, I powered the computer off.

[1] ubuntu claims I have had lockups when I login, but If i didn't see them. I don't care if the screen locks up for a microsecond. This was different since minutes went by.
