journalctl --system --since "1 hour ago"

After upgrading my Leap 42.3 system to Leap 15.0 it takes very long to boot up.
Of that time, around 1.5 minutes (1:34) is spent on initrd-switch-root.service
while it seems the system is doing nothing (at least the hard disk light stops
blinking for all that time).

The system stops just after:

Jun 05 18:32:41 geeko systemd[1]: Switching root.
Jun 05 18:32:41 geeko systemd-journald[154]: Journal stopped

And then continues with:
Jun 05 18:34:16 geeko systemd-journald[154]: Received SIGTERM from PID 1
(systemd).
Jun 05 18:34:16 geeko kernel: systemd: 20 output lines suppressed due to

Jun 05 18:34:16 geeko apparmor.systemd[420]: Restarting AppArmor
Jun 05 18:34:13 geeko systemd[1]: Execution failed: Protocol error

Note the systemd log from 18:32:43 being written after other logs from 18:34:16
and the "Execution failed: Protocol error" message which might be related.

I tried enabling debug-shell.service, but that is started after systemd
unfreezes. I attach the full output of journalctl --system --since "1 hour
ago". Btw, for some reason, in this system, journalctl only shows the journal
logs from the current boot, never showing logs from previous boots. 

Also, just in case it rings a bell, I also have this problem on the same
system: https://bugzilla.opensuse.org/show_bug.cgi?id=1096050
