--- Comment #5 from Matt Coffin <mcoffin13 at gmail.com> ---
I can reproduce this in a very very specific way (discovered while reproducing
bug 102322).

With the amdgpu driver, and RADV vulkan implementation, with DXVK 1.2.1,
running "House Flipper" from Steam (wine-staging 4.8), on 2560x1440 144Hz
display (DisplayPort). It crashes with the AMDVLK implementation as well, but
with a different message.

Usually happens withing 2 minutes of firing up the game. It's notable that this
*does not* occur if I render the game in 1080p and blow it up for the screen.

* 5.1.3-arch2-1-ARCH
* LLVM 8.0.0
* vulkan-radeon/mesa 19.0.4

The register that it is not liking the access to flips between TC1 and TC2
seemingly nondeterministically.

I'm sorry for the poor information, but I'm not used to developing/debugging
software at the kernel level. Let me know what information I can provide to be
helpful, and I'd be happy to fish it out for you. Thanks in advance for your
work and the help.
