[Bug 1855496] [NEW] Attempting to open a tty session when plymouth is showing the boot process causes the entire system to be frozen in an infinite loop until I shut down via the power button.

[Seija Kijin]

Public bug reported:

Whenever I press Ctrl+Alt+F3 when the computer is showing the boot
process or the ascii text for ubuntu, the entire system freezes, even
the mouse cursor, and I am forced to reboot the machine.

I expected the boot to continue and then open a tty session once the
system finished booting, not a complete freeze or lockup.
