Comment 9 for bug 1829402

>1. Does the problem occur if the system is completely powered off between reboots (as opposed to what >is called a 'warm' reboot) ?

Yes.

>2. Can 'journalctl --list-boots' be used to identify logs of a *failed* boot and use 'journalctl -b X' to grab the log file of the failed boot?

Yes.

boot -1: (cold powered off state, been powered off for some hours)
This was a successful boot without doing anything.

<There was a purple screen hangup boot but i guess that was not recorded>

boot 0: (powered off by long press power button, get to bios, esc to get grub, edit a recovery menu entry, delete 'recovery' add 'nomodeset', to be able to boot)
