I can confirm that this commit was the problem in my case. That commit introduced a boolean error in src/gallium/drivers/radeonsi/r600_texture.c which was later fixed in 49f2ba2c. My Mesa build on Sep. 2 was before e8f9195e, and on Sep. 6 was after. The new Mesa I built today was only failing because my LLVM 3.4 did not include the necessary patch for Marek's transform feedback work. Once I update LLVM, no GPU failures were observed and all was well again. Hopefully José will have no more problems if he gets a new version of Mesa at or after commit 49f2ba2c. If he uses a version after 2b71b3d4, he will need LLVM 3.4 at svn190575 or later.
