Hi!
Kernel 6.4 won’T boot successfully, I assumed something related to TPM (can’t enable/disable in BIOS, as Coreboot installed, so I simply pulled the TPM), but that didn’t help.
Here the journal for unsuccesfull boot:
https://paste.opensuse.org/pastes/eaa75b863a28
Kernel 6.3.9 boots just fine:

Both logs stop at the same line and the log lines are truncated. Always use
journalctl --full --no-pager
when posting journalctl output. But if kernel fails to boot it is unlikely journal will contain the reason, you need to capture console output.
Hi and many thanks!
This is what it looks like when boot freezes:

Helpful???
The kernel has booted. Did you try Ctrl-Alt-F1 or Ctrl-Alt-F2 if you get login prompt?
Otherwise boot with plymouth.enable=0 and without quiet on kernel command line, it may show more information.
it was without quiet and there is no plymouth in the kernel boot line
https://paste.opensuse.org/pastes/259cb370d8f9
The machine doesn’t even respond to REISUB. No VNC, no ssh. Nothing. Have to pull power cord…
So what? On boot plymouth is started and hides kernel messages.
I added “plymouth.enable=no” to kernel boot line, absolute identical output on screen, do you need a photo or do you believe me? 
as the last output is network is down: might there be a problem with “ipv6.disable” in the kernel line?
Are any keyboard LEDs blinking at this point?
nope, all black … …too short to post… sigh…
Try adding debug to kernel command line.
With this kernel line
https://paste.opensuse.org/pastes/28c3e76b2d3a
the boot goes 1 step further before freezing:
https://paste.opensuse.org/pastes/28c3e76b2d3a
and once (!) I had a flickering screen at that stage that rebooted automatically within 3-5 sec. Graphics?
Are doing it on purpose? Where did I say to add this parameter?
debug doesn’T add anything meaningfull before the “authorization manager” message, just some “systemd-journal… Successfulyl sent some stream file descriptor to service manager” spam above…
in your second post in this thread?
You posted the same picture of bootloader screen.
OMG, really? It was with plymouth.enable=0, no quite, no resume, no ipv6.disable…
Yes, it was the first link in your post. And the second link sounded like it would be screen when freeze happened. Try to look yourself.
sorry, the boot ends here with plymouth.enable=0, no ipv6.disable and no resume

The screen flicker and reboot is not reproducible on kernel 6.4 and doesn’t occur with kernel 6.3.9
What should I do with that?
Can you boot into single user or multi-user? Just add a single s or 3 to kernel command line.
