Description:
After a recent update and reboot, due to linux the 5.9.12.arch1-1 -> 5.9.13.arch1-1 update that hit the core repos recently logging into the TTY session fails.
Once the system finishing booting the getty process successfully restarts and displays the login prompt as expected, but after entering my username and pressing the Enter key instead of being prompted for my password it seems as though the getty session gets restarted and I'm again prompted for my username. I have since rolled my system back to a backup from before the update was done and everything is working again as expected but due to this I have lost any system logs that may have given any pointers as to why getty was crashing/restarting after I entered in my username. This happened for both my normal system user and when trying to login as root.

Without logs, there nothing to be done here. I would guess you're using bash and it wouldn't run, but who knows.

Well the root user on my system is using bash for the login shell yes, but my normal user is using a different shell (Elvish) for its login shell so I doubt that is the issue as the same thing was happening with both users. Plus unless the getty process tries to spawn a new shell instance between prompting for the username and the password that doesn't seem to make any sense why the getty process would restart before it could ask for my password.

If the login shell crashes/refuses to start, it will log you out, so it would make sense. Since the user isn't on bash, though, it may not. We're back to requiring logs. Honestly, though, since there hasn't been a big outcry, I'm guessing this is a local issue better solved on the forums, IRC, or mailing lists.

As I need this machine for work I'll hold off trying another update until this weekend and if it happens again then I'll grab the logs before rolling back again and go from there then.

Let's follow up on the support channels at that point. I'll close this for now and you can request that it be reopened if it's determined to be a package issue.
