LLVM register allocation bug
Seriously, this bug is the last really important hindrance for ditching Catalyst and switching to RadeonSI for real
My kids were having trouble with constant lock-ups of the complete computer when playing under Ubuntu 14.04 with Catalyst - requiring a hard reset. Also I bought the fabulous Goat Simulator which has just been released on Steam, but that had ugly artefacts and blinking. Last night I tried updating to Catalyst 14.6 - but that didn't really solve any issues. (*Crap*)
Then I tried going back to the RadeonSI, but e.g. Kerbal Space Program was running like a slide show. After updating with Oibaf's PPA everything seems to be running really smooth now - except Goat Simulator, which barfs with the LLVM register allocation bug. Boot sequence and switching in/out of fullscreen games is much smoother now. No total system freezes yet.
Quick rundown of Ubuntu 14.04 with Oibafs PPA per 2014-06-28. (Intel i5-3570K with AMD HD7750)
I really, really hope they manage to wrap it up before Ubuntu 14.10

- Kerbel Space Program Demo - Works fine!
- Portal 2 - Works fine!
- Goat Simulator - Crashes with the LLVM register allocation bug
- Trine 2 - Works fine!
- Antichamber - Works fine!
- Minecraft - Works fine!
- Warthunder (under Wine) - Works sort of OK (Similar to Catalyst)
I really, really hope they manage to wrap it up before Ubuntu 14.10
