Please note that more people report crashing on radeonsi after some time of playing: http://forums.unknownworlds.com/discussion/comment/2330666/#Comment_2330666 This is with "Failed to allocate" errors.
I know (and if you compare the system info, you'll find a lot similarities ... ;-)
For me personally, NS2 didn't even start on older Mesa (mmap failed), now it starts, but as people report, seems to crash after some time. I personally never played that long (because loading the shaders takes an eternity).
Yeah, same here, just go it to load wite mesa 13 and llvm 3.9.1. With regard to loading times, I guess shader-on-disk cache should help here...
I'd guess this is simply the game running out of 32bit space, and Mesa drivers being more memory hungry than proprietary drivers. The devs had OOM problems even with nvidia drivers in the past and had to cut down on memory usage. They said they can't even add more skins because they're that close to the RAM limit. They are working on a 64bit version of the game, which should hopefully fix all this.
