# Notes
I encountered multiple random GPU hangs on this game before (~1 every 5 hours), but the latest update added an alternative third-stage level where I could not play longer than approximately 2 minutes without encountering a hang.

Unfortunately, the GPU does not recover, and I have to force-reboot the computer.

Do not hesitate to ask me additional information, with steps on how to gather it.
I thought about recording an apitrace, but this probably wouldn't play well with the GPU hang. I am not sure whether the issue is in LLVM or this should be preventable at the amdgpu-level. Though GPU recovery should probably work in the first place (I saw a patch to improve this pass by, but didn't try it).

Another game I'm getting random hangs in is No Man's Sky, also unrecoverable. I am reporting this one since it seems to be more reproducible.
