drmn0: error: GPU lockup CP stall for more than 10000msec

[Michael Jung]

This has happened twice so I thought I would report it.  I believe all 
the required info is available in the links below.

X.Org X Server 1.12.4 / 10.1-BETA1 #0 r271460

I was simply building ports when X11 puked, the console flipped back to 
VT and tried to fire up X11 again.  This happened over and over until 
reboot. I did not try unloading the kernel modules and reloading them. 
Please advise what else to do or to collect should this happen again.

Lastly, I have been using the VESA driver for a long time on this 
hardware.  I just starting using the new ATI driver and VT console.

Thanks.
