--- Comment #6 from Bryan Quigley BryanQuigley@Ubuntu.com 2012-06-04 07:37:58 PDT --- I did test with a 3.2 and the same 3.4 kernel and the stable mesa/X/drivers that came with Precise. This did not cause a crash..
I think I tested with 3.2 and the git mesa/X/drivers will cause the crash, I'll confirm tonight.
