Created attachment 145366 [details] apitrace of Hearts of Iron IV hard lock

Apitrace from hard lock playing Hearts of Iron IV without Steam. The replay from this trace will hard lock the computer, though inconsistently. I've replayed the trace three times. The replay hard locked computer one time.

neofetch from hardlock:

OpenGL version string: 4.5 (Compatibility Profile) Mesa 19.1.6

Note: hard lock replayed occurred when the Discord flatpak is also running.

I also noticed some errors that pointed to discord in my logs. In my case discord was installed via .deb package. Could you please try and disable hardware acceleration in discord settings - appearance menu? Please let me know if it helps or changes anything. Thanks!

I have disabled hardware acceleration in discord settings to see if that improves my experience and report back my results. I am doubtful that it will help much. At least on the 5.2.11 kernel, I had lockups with or without discord running. Discord running just seemed to make the problem appear more consistently.

Another lockup and crash last night of Stellaris with identical dmesg kernel information as comment 105.

Kernel for this crash: 5.2.17.

Unlike previous attempts, I also had cpupower configured to run the cpu in performance mode and was running feral gamemode. Although I still wonder if my hardware has an issue, I am able to run Stellaris without issue under Windows.

Final Note: Getting an apitrace of my crash under Stellaris is not feasible for two reasons. First, the crash typically happens between 30 minutes and 40 minutes of game play, resulting in a monster trace file. Second, i cannot get apitrace to run correctly with Steam and a 64-bit game, which is necessary since the crashes happen most frequently in multiplayer.

I am happy to provide more data if someone can point me in the direction to capture it. Aside from trying the amdgpu-pro drivers, is there anything else I can try?
