Screen simply becomes black (no signal) and machine is dead, leaving a hard reset as the only option. The dmesg is flooded with the following lines: radeon 0000:01:00.0: GPU fault detected: 147 0x0d859002 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x000012D8 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x05090002 [...] repeated a hundred times with only the first line changing a bit [...] then: radeon 0000:01:00.0: GPU fault detected: 146 0x07151004 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000 [...] repeated a hundred times with only the first line changing a bit [...] Times indicate this goes on for approximately two minutes before the hang.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
