My Debian Sid (KDE) OS (on a PC with an Nvidia GTX 970, proprietary drivers, an i7-8700K CPU, and 16GB RAM) has begun freezing randomly. Once or twice a day, it's completely unresponsive; the mouse won't move, and SysRq does nothing.

This began after upgrading a bunch of packages. I checked syslog but nothing sticks out at me. Does anyone have any ideas on what could be wrong, or advice on how I can debug the issue?

    @K7AAY I don't think there are any messages in there during that time, 12:03:17 is when I rebooted after the freeze. I added that part of the file in an edit. – pcfreeze May 17 at 1:38

In case anyone is interested - I tried several things:

  • bios update
  • memtest came up clean
  • switch to Cinnamon
  • downgrading nvidia drivers to previous version
  • setting intel_idle.max_cstate

and some other less notable things. Eventually I compiled a newer version of the kernel and have had no freezes for a few days.

nvidia sucks. Use stock-drivers instead of the NVidia ones.
