I (In reply to Marek Olšák from comment #17)
> This seems to be fixed with current Mesa git. Can you confirm?

It looks like it is not fixed in mesa git as I can reproduce it with the
apitrace in comment #c29 with Cap Verde, radeon driver, mesa 18+, kernel
4.15.0-15-generic, LLVM 7.0.0, xorg 1.20.99.1, xf86-video-ati 18.0.1.

(same result with kernel 4.4, mesa 12.0.6, llvm 3)

radeon 0000:08:00.0: GPU fault detected: 146 0x0d64520c
radeon 0000:08:00.0:   VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x001196EB
radeon 0000:08:00.0:   VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0405200C
VM fault (0x0c, vmid 2) at page 1152747, read from CB_CMASK (82)

I always get the errors above and sometimes I get the gpu lockup and also
sometimes the Packet0 not allowed!.

The possible fix in #c10 does not help.
