[Bug 415357] Re: [gm45] [Karmic] Intel Graphics: Xorg consistently crashing when using some applications

 

I can reproduce this on my ThinkPad X200s with exact instructions from
Diego. I get the same backtrace in /var/log/kdm.log and I have also
noticed the following oops in my /var/log/messages file:

Bryce: since this problem is easily reproducible, should we submit it
upstream?
