Thanks for raising the bug. Please help us with the cloud-init logs by running `sudo cloud-init collect-logs` and uploading the resulting file.
The logs will help us see what could be the issue leading to this.
I am changing the status to 'Incomplete', please change to 'New' when you provide the logs requested.

Title:
  output from dmesg (log) interferes with login

Status in cloud-init package in Ubuntu:
  Incomplete
Status in systemd package in Ubuntu:
  New

Bug description:
  On Ubuntu 22.04 Server but also affects earlier releases the login
  prompt gets masked and/or interfered with by outputs from dmesg or log
  outputs on screen. The package being used is version 249.11-0ubuntu3.9
  (systemd) and 23.2.1-0ubuntu0~22.04.1(cloud-init).

  These can come from official software (cloud-init) but also from
  partner's software (e.g. hp-ams and/or amsd). It really interferes
  with logging in through KVM either through remote means or local, but
  not over SSH. Including HPE's iLO and Dell's iDRAC.

  It's especially problematic when trying to type the password after a
  reboot or cold boot.

  What I was expecting was for those outputs during login prompt to be
  logged to log file only, to be accessible afterwards via dmesg or
  equivalent.

  What happened instead was issues with repeated incorrect password or
  username due to the masking of what displayed on screen.
