Title:
output from dmesg (log) interferes with login
Status in cloud-init package in Ubuntu:
New
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.
