tty0 should be ttyS0 now I believe. Where this is changed with images using systemd I am not sure, but with SYSV this was changed in /etc/inittab.

Yes, tty0 now identifies as ttyGS0.

After fighting it for several hours, I went to lunch.
When I return, the problem has disappeared, is no longer reproducible, and everything is working fine.
I didn’t knowingly do anything to fix it.
So, I guess disregard the BugReport.

Anyway, in the future, I will try having more lunches when problems occur.
