On a couple of occasions now whilst using firefox I've had the GPU lock up on me.
[ 60580.875] [mi] EQ overflowing. Additional events will be discarded until existing events are processed.
The laptop hasn't been suspended, but has been on for 17 hours and has had the browser open all that time. This is the 2nd or 3rd time this has happened in the last week. Pretty sure I'm always in Firefox. Tabs include gmail, twitter, google calendar (x2), facebook, youtube, google docs, Google+ and a few intranet pages. I recently watched an embedded youtube flash video - a few minutes before the crash occured.
I'm using unity 3d, and also have thunderbird, a terminal, tomboy and shutter open.

[ 60580.927] [mi] mieq is *NOT* the cause. It is a victim.

Had this again, triggered when someone gave me a link to a G+ page which contains an embedded flash (youtube) video and some photos. I was able to play the short video but the display became very laggy and eventually unresponsive.
