I have the same issue, and I also found some other report of it:

http://askubuntu.com/questions/614867/frequent-xorg-crashes-with-radeon-r9-280x
https://bbs.archlinux.org/viewtopic.php?id=186388

I'll try the workaround proposed in
https://bugzilla.kernel.org/show_bug.cgi?id=62721
(adding "radeon.hard_reset=1") and see if that helps.
