Hi, the kernel with this fix for Bionic is present in the -proposed repository,
the version is 4.15.0-46-generic. To enable proposed packages, you
can check [0].
Alternatively, you can install version 4.15.0-43-generic, which does not
have the offending patches that caused the tty issue.
Cheers,
Ubuntu 18.04.1 LTS Server (GNU/Linux 4.15.0-45-generic x86_64)
