I'm 99% certain it's being caused by my external USB dock starting up.
See my reply to Ed. The dock is not mounted at boot, but has a BTRFS
filesystem that (possibly) the kernel insists on checking before the
rest of the startup can proceed. This is speculation at the moment.
systemd-analyze blame shows a long delay in a unit I created to
automatically power down the dock if it's not mounted:
$ systemd-analyze blame|head
4min 18.016s dock-watch.service
30.517s systemd-udev-settle.service
15.273s logrotate.service
6.274s NetworkManager-wait-online.service
5.765s raid.mount
5.452s plymouth-quit-wait.service
5.038s akmods.service
4.541s upower.service
4.427s sssd.service
I've uploaded the dock-watch unit and the scripts it calls, together
with the automount unit, to:
