Given
Trying to run Mario Kart 8 in Cemu under wine with a Vega 56 or 64,
When
Opening the game (US or EUR, I have EUR, other people have tested US),
Then
The system freezes once the Mario Kart 8 splash screen shows up. Keyboard/Mouse
input is gone, only ssh sessions remain open until the system is hard-rebooted.
There is no other way to recover from this.
This can be reproduced every time with a Vega64 or Vega56 card. It has been an
issue since at least kernel 4.15, mesa 18.0.
I have tested on 2 systems, and several people with Vega cards get this issue
(works for nobody).
uname -a
Linux nihonium2 4.18.1-arch1-1-ARCH #1 SMP PREEMPT Wed Aug 15 21:11:55 UTC 2018
x86_64 GNU/Linux
I'm running antergos with mesa-git, fully up to date.
dmesg, glxinfo are attached.</pre>
