Oof. I updated my workstation today (Arch) and it locked up hard several times since. I switched from i3 to dwm and it seems to have worked around the problem temporarily.
Still getting the hard lockups with dwm. This isn't good, but I don't want to spend time troubleshooting right now. I'll do more non-computer things for the next couple days.
@daremo running a compositor? Try turning it off.
Also: memtest if you can.
@nathand No compositor. Thanks for the memtest suggestion. I'll try it tomorrow.
