Hi, my name is Sunie and I'm suffering from this error. (might as well turn this into a self-help group right about now, right?! :P)

But yeah, chipping in. AMD 7870, started around 2.3 and crash in Camp Dragonhead and Mor Dhona near the Coerthas/Mor Dhona zone line. Teleporting guarantees a crash after a bit of play time.

I've applied the work around so I hope I'm safe for now, but this is really annoying. I'll like the OP as Critux suggests, as well.
