Title:
  Groovy kernel (5.8.0-1004-aws) creates broken /dev/console on i3.metal
  instances

Bug description:
  Hi,

  When running Groovy daily images on i3.metal instances a broken
  /dev/console is created. The char device appears to be writable but
  writing to it causes an Input/output error. This is breaking cloud-
  init, as it tries to log to /dev/console, and is likely to break other
  programs.

  On Focal:

  root@ip-172-31-24-163:~# ls -l /dev/console
  crw------- 1 root root 5, 1 Sep 21 16:07 /dev/console
  root@ip-172-31-24-163:~# echo x > /dev/console
  root@ip-172-31-24-163:~#

  On Groovy:

  root@ip-172-31-20-184:~# ls -l /dev/console
  crw--w---- 1 root tty 5, 1 Sep 21 16:03 /dev/console
  root@ip-172-31-20-184:~# echo x > /dev/console
  bash: echo: write error: Input/output error

  The Groovy kernel log has a

  [ 3.561696] fbcon: Taking over console

  line in it, which is not present in the Focal kernel log
  (5.4.0-1024-aws). Perhaps fbcon should be prevented from taking over
  console?
