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?
