Hello, While trying to test new tessellation code in radeonsi using Unigine Heaven, I happened to stumble on this bug. After first few frames of rendering after the loading screen ends, the system locks itself up. The rendering is almost always broken too. Sometimes the GPU does try to restart, but most of the time the lock-up is hard (the kernel doesn't respond to any keyboard events) and I need to reset. After the reset, the following messages reside in the kern.log (quite a lot of them): [ 142.631214] radeon 0000:02:00.0: GPU fault detected: 147 0x0a0d4402 [ 142.631217] radeon 0000:02:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00130CD0 [ 142.631218] radeon 0000:02:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0D044002 [ 142.631220] VM fault (0x02, vmid 6) at page 1248464, write from TC (68) This could be related to #90266, but the faults don't happen in the background, they almost immediately take the system down. I am using kernel 4.1.3, mesa and libdrm from git, xorg 1.17.2, ddx 7.5.0. The problem also did happen just before the tessellation work was done (with the tessellation disabled in the benchmark), using mesa from ~2 weeks ago. The recent Marek's fixes didn't help. Relevant Heaven settings: Quality: Ultra Tessellation: Extreme/Disabled Anti-Aliasing: 4x/8x Full Screen: yes
