> Reboot for an upgrade happens by holding a spin lock until it overheats and reboots. This happens every time on multiple computers so I think it's intentional(?) but the crash reports are pretty wild.

That's a watchdog kernel panic (maybe). Shouldn't be seeing that unless you have misbehaving NFS mounts or something.

Yes, it's a watchdog kernel panic which takes place after the fans spin up. No NFS mounts here.

I have them happen too (for no particularly discernible reason)

Well, you can always set up a coredump server and report it with Feedback Assistant…

I do this dutifully with each reboot.
