reboot/shutdown phase

I have my workflow on Debian/Sid, with kernel compiled by, currently at version 5.14.1, on asus x555ln notebook.

The problem occurs when the external USB 3 harddisk is disconnected from
itself: in some cases it is no longer reconnected and if I try to do "sync"
from console, this command appears freezed.

If I reboot, at the end the system log shows that it has reached the
"Rebooting" phase but remains in loops on the message indicated above (see
image file).

When this happens, the system should recognize that the harddisk is no longer
available or stalled, to interrupt the write of the cache and terminate the
reboot or shutdown phase.
