Hi, Please find attached the error log, for future reference.
Forgot to mention: I could still use the system after this error, so it was not a complete fatal error in that regard. All active processes (mostly rsync) were hanging in state D though, so I couldn't kill them anymore. Also the FS was not umountable. So I still had to reboot. Thanks, Erik.
