Hello Nikolaus,

I sent the logs yesterday, sadly from a different mail account, therefore the mail did not pop up on the mailing list.

Than I played around with 'git bisect' in the letux-5.7-rc3 branch and found that the problem is caused by one of the letux patches.

If I revert the commit (git revert af2ece0e31746f2c1a2cc513da54c8f9cee27042 -m 1) on top of letux-5.7-rc3 the console gets to the login prompt.
Sadly the login does not work because of no password prompt

Best regards
Stefan
