Gone Home and Unigine Heaven 4.0 lock up my system after a few minutes of operation when using this ppa: https://launchpad.net/~oibaf/+archive/graphics-drivers/
When using mesa 9.2.1 provided in ubuntu 13.10 this does not occur with Gone Home. Same lock up issue happens when using ubuntu 14.04 development with mesa 10.0.1. In all cases I had radeon.audio=1, radeon.dpm=1, and R600_DEBUG=sb.

Journalctl of the crash
I confirm that this also happens on my Sapphire hd 6750 1Gb gddr5 Juniper. Playing graphically intensive games for few minutes ( like Left 4 Dead 2 or Dota 2 on high) completely crash the system. I attached the best log of the crash I found. I'm using arch linux 64 bit, kernel 3.12.6, mesa 10.0.1.
Does it work ok if you disable hyperZ? R600_DEBUG=nohyperz
The problem still occurs for me when using R600_DEBUG=nohyperz.
After disabling hyperz my card no longer crashed. I guess it's a problem with this feature.
Unigine Heaven 4.0 tested on 6550D with and without R600_DEBUG=hyperz.
I didn't noticed performance boost, but no glitches, crashes or anything. Worked well.
appletorch, could you please test current Mesa git and see if it's fixed?
Please don't forget to set this environment variable:

Will do once I have a working monitor again, hopefully by the end of this week.
Unigine Heaven ran without issue. Gone home was giving me segfaults when trying to start it on my new installation so I wasn't able to test that.
