--- Comment #24 from Linux Tester <linux.tester at sharklasers.com> ---
After some updates to MESA and kernel this bug no longer happens at all - 2D
now rock solid for me on R9 270 and I can run even most troublesome workloads
for weeks without any issues. While I failed to pinpoint what exactly has fixed
bug, thanks anyway. I think it is now safe to close this bug as fixed. I bet
you've got dozens of other GPU lockups to chew on, so I'm glad to inform you at
least one nasty thing has been nailed down.

(it's me, original bug reporter who has forgot password on both original
mailbox and bugzilla account, dammit)
