--- Comment #6 from almos aaalmosss@gmail.com 2011-08-03 05:22:44 PDT --- I observed that this corruption is often accompanied by these messages on the console from which I start a game: radeon: mmap failed, errno: 1 Mesa: User error: GL_OUT_OF_MEMORY in glTexImage radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1 radeon: mmap failed, errno: 1
Some of the corruption disappears after a suspend-resume cycle. Can this be a memory-accounting bug?
A possibly unrelated question: what happens if the scene to be rendered needs more than VRAM+GART amount of data?
