Out of nowhere, my OS froze, failing to respond to anything but the SysRq reboot.
The following was logged:

The log went on to record the fact that I unplugged my mouse and plugged it back (I first thought that was the problem), so the system wasn’t completely frozen, only the screen was (and Ctrl+Alt+F1 did nothing). I missed the chance to attempt an SSH connection, should I try that and do anything in particular in case the problem reappears?
