Comment 7 for bug 1023916

I had this same bug and it appears to have been fixed already in the latest version. I have upgraded to 8.98 from xorg-edgers and have not had an OOPS recurrence in over a week. It was previously a couple times a day, often triggered by interaction with a flash plugin.

As a reference point: I did not experience this OOPS until I added a second video card to support a dual-head setup.
Both cards are HD 6870.
