Hello. I am using the obiaf PPA which is mesa 10.3 git compiled with LLVM 3.5. 
My syslog and kern.log spam the error messages below. They filled up my entire
hard drive with this error, and the spam occurs constantly. It appears to speed
up and only fills the hard drive when in 3D mode. I am using a Radeon HD 7950.



kernel: [41138.121106] [drm:radeon_gem_object_create] *ERROR* Failed to
allocate GEM object (0, 6, 4096, -22)
kernel: [41138.121121] [TTM] Illegal buffer object size
kernel: [41138.121123] [TTM] Illegal buffer object size


Thanks for the help.
