I am also experiencing this issue.

* Kernel: 5.1.3-arch2-1-ARCH
* LLVM 8.0.0
* AMDVLK (dev branch pulled 20190602)
* Mesa 19.0.4
* Card: XFX Radeon RX 590

I've seen this error, bug 105733, bug 105152, bug 107536, and bug 109955 all
repeatable (which one each time appears to be non-deterministic) with the same
process.

I just launch "House Flipper" from Steam (DX11 title), with DXVK 1.2.1, on
either the mesa RADV or AMDVLK vulkan implementations.

At 2560x1440 resolution (both 60Hz and 144Hz refresh rates), the crash(es)
occur. At 1080p@60Hz, I get no crashes, but they come back if I disable v-sync
and framerate limiting.

I logged power consumption with `sensors | egrep '^power' | awk '{ print $1 " "
$2; }'`, and found that the crash often occurs soon after the card hits its
maximum power draw at around 190W.

I don't have much experience debugging or developing software at the
kernel/driver level, but I'm happy to help with providing information as I go
through the learning process here. I'll compile the amd-staging-drm-next kernel
later tonight and post some results and logs.

Please let me know if there's more information I could provide that may be of
use here. Thanks for your hard work!
