https://bugs.freedesktop.org/show_bug.cgi?id=80419 --- Comment #141 from Alassane Maiga --- Well I can reliably make it stop locking the system completely now. I switch to console with ctrl+alt+f2 as soon as the game locks up and then back as soon as the ring stall messages start to fill up the screen. When I am back the game is not frozen anymore, but extremely slow. In fact all opengl related rendering becomes slow. And I get this message each time I switch to console : "GPU fault detected 146 0x0904xxxc VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00029E48 VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x040xxxxC" How should I give more information? If I restart the performance comes back to normal -- You are receiving this mail because: You are the assignee for the bug.
