Public bug reported:
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

state.
Jan 10 13:12:34 systemd[1]: systemd-modules-load.service: Failed with result
'exit-code'.
