I can easily reproduce it by sleeping for >5min, so the systemd
watchdog timers are triggered. The patches don't revert cleanly, so I
didn't look into booting without them, yet. I will try just linking
the monotonic clock to the monotonic_active clock later.

Also, doesn't this hunk in 72199320d49d need a 'break;':
