dmesg output

I read about this site using WebGL and tried it in Firefox 4. http://kataspace.sirikata.com/
Then I got a GPU lockup. The computer seemed to recover fine though!
I could switch to console mode after waiting a bit and kill firefox.

Comment 1 Alex Deucher 2010-12-02 07:50:12 UTC 
Probably a 3D driver bug.  Can you try r600g?
Comment 2 Ernst Sjöstrand 2010-12-02 10:28:11 UTC 
With Gallium firefox crashes instead, nothing in dmesg.
Here's the crash report at mozilla:
http://crash-stats.mozilla.com/report/index/bp-94150985-0b10-41a8-b145-407ee2101202

For reference, with Gallium all of these work fine:

Comment 3 Ernst Sjöstrand 2011-01-25 12:55:53 UTC 
Closing this, the original issue with r600c is solved and there are newer and better bugs for the new problems.
