Hm, strange. I left for about 2 hrs and the system was frozen. So did a hard reset (I rebooted before multiple time to check if what I did worked). So it looks things are ok now, but I find some strange error messages in my journal: 15:19:32 systemd: Failed to start Sound Service. 15:19:32 systemd: Failed to start Sound Service. 15:18:47 systemd: Failed to start System Suspend. 15:18:47 kernel: Failed to put system to sleep. System resumed again: Device or resource busy 15:18:47 kernel: Freezing of tasks failed after 20.007 seconds (54 tasks refusing to freeze, wq_busy=0): 15:17:20 systemd: Failed to start RealtimeKit Scheduling Policy Service.
