GPU hang when playing most games
Doing anything to cause a super high load on my RX 5700 XT causes it to hang. Unigine Superposition, Elder Scrolls Online, Nier:Automata, Ark Survival Evolved, and probably other games all hang. When this happens all of my monitors go into power saving mode acting as though the system has turned off but I can still do everything as long as I don't need a GPU for it including logging in via ssh. I've attached a dmesg report about this. I'm on Debian sid with Kernel 5.5.3. I've tested this across 5.3, 5.4, 5.5, 5.6-rc1, and the current kernel.org master with mesa 19.2.4, 19.2.6, 19.3.3, and 20.0-rc2. Both OpenGL and Vulkan games are affected however outside of high loads the system works fine. Here is the dmesg output caused by Superposition: amdgpu.log. I'll try just about anything to assist with troubleshooting this further. I've tried running Superposition with
AMD_DEBUG=nodma but that does not make anything better. I've also tried
amdgpu.lockup_timeout=3000. Basically everything I've found on issue trackers doesn't seem to work as a workaround. I'm still not convinced this isn't a hardware issue as I ran Superposition when I first got the card but even recently I've had times where I can run it 3 or 4 times in a row no issue but then I reboot and can't even get through once.
