Clearly the docking unit isn't just doing this flakily on its own.
Something is making it happen, and I've no idea how to discover wha

I have a systemd automount unit that correctly powers up the dock when

After an idle time, automount unmounts the drives. A script detects

What kernel version? i.e. uname -r
At the time of the mount failure, what do you get for:
$ lsmod | grep xfs
xfs 1892352 0
$ dmesg | grep -i xfs
[ 717.658384] SGI XFS with ACLs, security attributes, scrub, quota,

I suspect you get neither of the above results.
