On a Kabini system using kernel 4.8-rc8, Mesa and LLVM git, running GROMACS OpenCL example 1536 from [1] results in radeon: Failed to allocate virtual address for buffer: radeon: size : 4096 bytes radeon: alignment : 4096 bytes radeon: domains : 2 radeon: va : 0x000000000948b000 radeon: Failed to deallocate virtual address for buffer: radeon: size : 4096 bytes radeon: va : 0x948b000 radeon: Failed to allocate virtual address for buffer: radeon: size : 4096 bytes radeon: alignment : 4096 bytes radeon: domains : 2 radeon: va : 0x000000000948b000 radeon: Failed to deallocate virtual address for buffer: radeon: size : 4096 bytes radeon: va : 0x948b000 This is one of the larger examples, so it requires more memory than the previous ones. I will test the largest example (3072) soon, and I expect it to crash the same way. This is a regression. It will be very hard to bisect LLVM and kernel on this machine as it is really slow, but Mesa is likely bisectable. Let me know if it is worth it.
