Broken: version: 2.83.12, branch: unknown, commit date: 1970-01-01 00:00, hash: rBunknown. 2.83.9 had the same problems, have not tested earlier 2.83 releases.
Short description of error
Blender crashes, and takes my whole system down with it. The problem is so severe that closing blender (pkill -9 blender) or restarting the window manager (i3wm) does not resolve it. The problem can only be resolved by a reboot.
Exact steps for others to reproduce the error
Run blender 2.83.12 on Fedora 32 with i3wm (no compositor). Start an empty project, use blender for a while. A random system-crippling crash will happen after between 1 min to 30 min of usage. The crashes seem unrelated to the things I am doing with blender (rotating the default cube could be enough).
Please note that a crash like this is unique for me. Other complex software (Unity, older versions of blender, gimp, firefox) run smoothly. Apart from Blender 2.83, I have never experienced crashes that required a reboot, for any software, in many years of linux usage. I realize that this is a hard one to debug, just hoping my report can help. I'm not sure where I can find any log files after a crash (and submitting those could be challenging with my whole system going down). Thanks :)
