I think this unresponsive pause is caused by the periodic execution of the
synchronize cache command. This causes the hdd to flush it's whole internal
buffer to disk, and can take some seconds. During that time, the hdd is busy.
I think it is a mistake to peridically execute it. It should IMO only be done
once when shutting down the system.
