Title:
Unable to login via tty
Status in linux package in Ubuntu:
Confirmed
Bug description:
I am using Ubuntu 16.04.
After upgrading the kernel from 4.4.0-141.167-generic to
4.4.0-142.168-generic I am experiencing problem logging in via the
tty. I am able to provide my username, but the terminal automatically
submit password before I am able to type it. If I start the computer
with the previous kernel (4.4.0-141.167) it works as expected.
I have done strace on the tty in both scenarios while performing the login
with the following command:
"sudo strace -p 1572 -s 1024 -vff -o tty-login-issue/login"
4.4.0-141.167-generic (works):

4.4.0-142.168-generic (fails):
https://gist.github.com/ivarconr/603409ad1f0a3343a7f44a854283befc
Let me know if you need me to provide any additional details.
