Public bug reported:
The drivers on AMD Radeon are extremely flaky now. They crash several
times a day with symptoms ranging from instant hard freezes to
flickering of the image followed by colors weirdly changing, e.g. the
drop shadows on windows turning bright red. During the latest crash, the
following was printed to dmesg several thousand times:
[ 2059.396715] radeon 0000:01:00.0: GPU fault detected: 146 0x0ea20804
[ 2059.396716] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR
0x00000000
[ 2059.396717] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS
