[Bug 852812] Re: [gm45] GPU lockup render.IPEHR: 0x78080003

 

Good morning, 
This bug does still exist. After about an hour of testing, my tester's game-play was ended by a GUP hang (see attached terminal output).  

Before this was reproduced, there was a similar problem, which may or
may not be related. Because I have no idea what happened, I'll talk
about it here. While the tester was playing, the X server crashed, and
the screen switched to a TTY-like session with kernel messages about the
error, and the kernel seems to have completely crashed. I believe that
the kernel crashed because the computer was taking no input. I couldn't
switch TTY Sessions or anything, I just had to do a hard reboot. Because
I had no X server,  the only valuable output I could get was by taking
pictures of the screen with my cell phone. I uploaded the images to my
site here: http://jdgregson.com/temp/ubuntubug/

Hope this helps. I will post this same comment on the bug report on
freedesktop.org, just to keep everything in sync.
