At least once a day there is an unexpected desktop freeze incl. mouse and keyboard. Even magic-sys-rq isn't possible, only hard switch-off. From smartmontools I can exclude a hardware failure.

I've found that gpu-manager and systemd fail to load kernel modules.
This is among the output of journalctl | grep modules
Jan 10 13:12:34 systemd[1]: systemd-modules-load.service: Unit entered failed state.
Jan 10 13:12:34 systemd[1]: systemd-modules-load.service: Failed with result 'exit-code'.
Jan 10 13:12:49 gpu-manager[791]: Error: can't open /lib/modules/4.4.0-57-generic/updates/dkms
