I've got an apitrace of Dota that reliably causes GPU faults on radeonsi on my Bonaire XTX. The trace: http://files.code-monkey.de/dota.trace (468797931 bytes). I'm running Mesa from master (8d2542fc9d5af4db355b67cc2a1ff2f413685a27) and can reproduce the problem with kernel 3.18.2 and 3.19.0-rc2 (built from airlied's drm-fixes tree; 79305ec6e60d320832505e95c1a028d309fcd2b6). agd5f's "fix VM flush" patches from 2015-01-06 don't help either. Example kernel log excerpt: radeon 0000:01:00.0: GPU fault detected: 147 0x000c4801 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x01000000 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0C048001 VM fault (0x01, vmid 6) at page 16777216, read from 'TC2' (0x54433200) (72) radeon 0000:01:00.0: GPU fault detected: 146 0x000c080c radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0C00800C VM fault (0x0c, vmid 6) at page 0, read from 'TC0' (0x54433000) (8)
