Hi!
I had reported some time ago that Qubes OS hangs quiote some time (1 min 30 sec) on shutdown. It seems some process isn't terminating properly.
For some time I noticed this message in the journal:
systemd[1]: /usr/lib/systemd/system/mdmon@.service:28: Unit configured to use KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update your service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.
Could it be related? I have two Intel Matrix Storage Manager (IMSM) RAIDs on my machine, and one RAID used LVM and an encryped partition that is not used by Qubes OS...
Kind regards,
Ulrich
