(possibly DMA copying issue strikes back?)

After some investigation I got idea why bisect never succeeds. It looks like there was no stable kernels at all: 3.15 is also broken. However it takes "almost forever" to crash it with previously used methods. Somehow I stepped up on similar but far more optimized use case (another map in BfW game) which locks up GPU in matter of seconds to a minute. That's what I need :). This also proven to knock down "good" 3.15 kernels in matter of 30 seconds or so. So it was not good at all. Obviously my bisect can't succeed. On other hand now I can try mentioned patches... -- You are receiving this mail because: You are watching the assignee of the bug.
