Hello,

I've run into a bug wherein AMDGPU hangs as mesa 19 does something it doesn't like in particular applications. Mesa 18.3 is totally fine, as per padoka stable ppa. Padoka unstable and Oibaf both crash.
OpenGL like team fortress 2 seem to be fine but Vulkan (DXVK) wrapped applications  will just bury the whole GPU.
Even steam itself seems to hard lock when I start it which I can sidesetep by allowing GPU recovery with the kernel parameter and proceed. It does not recover when I start something vulkan and graphically intensive from steam itself.



Below is my dmesg from the card. This may be an issue with mesa or it may be AMDGPU, I am very curious as to which as this has affected me for about a month now across both Arch Linux and my new Ubuntu install, making mesa git unusable on my new card.

To make matters worse there is an issue wherein the EDID is messed up on boot with amdgpu.dc=1, worth mentioning if it's part of a deeper issue in AMDGPU.
