The systems completely locks up so > you can't use the keyboard and switch to tty9? No, that's not what happens. I mean that doing a reboot using ctrl-alt-del isn't possible. Switching VTs is no problem, but except for VT1 nothing was being shown. But maybe I overlooked things when I sent you the previous reply: see below. > That would sound like a kernel problem. > > might my problem not simply be some timing problem? > > Can you make a screenshot or a video from the boot process with "quiet" > removed from the kernel command line. I did. Not only that, I also tried to reboot again and this time I was able to run the commands you asked before from tty9: systemctl status systemd-analyze dump journalctl -alb This time the debug shell prompt was available at tty9, although booting failed. And in line with my previous findings, systemd-analyze and journalctl weren't available, as they live in /usr/bin, and /usr hadn't been mounted. But after mounting /usr from tty9 and then using the mount command systemd-analyze and journalctl were available, so I also have the output from those commands for you. The output, and the mp4 movie I made during the booting process are a bit too large for the e-mail, but they are available for download/inspection at https://www.icce.rug.nl/systemd/ Cheers, -- Frank B.
