[SOLVED] No console output after "initialising ramdisk" after upgrade from 8.0 to 8.1

After upgrading from 8.0 to 8.1, I only got a couple of log lines in the console after rebooting. It stops at the message about initialising ramdisk.

I therefore assumed it had hung, rebooted fine in a 6.2 kernel, and checked previous boot logs, only to find no errors.

I then rebooted with the default 6.5 kernel, and could see that actually I could log in fine via the webUI.

I therefore compared log messages between the two boots, and found no differences in errors or warns.

What I did find in the 6.5 boot logs was the "fbcon: Deferring console take-over" and "switching to colour frame buffer" messages were missing.


Code:
// Previous boot on 6.2 kernel that showed console
journalctl -b -1 | grep -i consol
Nov 27 18:44:48 pve-pc kernel: Console: colour dummy device 80x25
Nov 27 18:44:48 pve-pc kernel: printk: console [tty0] enabled
Nov 27 18:44:48 pve-pc kernel: fbcon: Deferring console take-over
Nov 27 18:44:48 pve-pc kernel: fbcon: Taking over console
Nov 27 18:44:48 pve-pc kernel: Console: switching to colour frame buffer device 128x48

// Boot with default 6.5 kernel that only shows console for a couple of lines and then stops
journalctl -b | grep -i consol
Nov 27 18:49:50 pve-pc kernel: Console: colour dummy device 80x25
Nov 27 18:49:50 pve-pc kernel: printk: console [tty0] enabled
Nov 27 18:49:50 pve-pc kernel: fbcon: Taking over console

did you regenerate your initramfs with simplefb included?
