Chris (~iplayfast): You're not running the latest HWE kernel image: linux-image-generic-hwe-18.04 | 4.18.0.18.68 | bionic-updates
"cat /proc/version" would report: Linux version 4.18.0-18-generic (buildd@lcy01-amd64-006) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #19~18.04.1-Ubuntu SMP Fri Apr 5 10:22:13 UTC 2019 If you would like assistance with this, please consider the commercial https://www.ubuntu.com/support/community-support and community https://www.ubuntu.com/support/community-support support offerings rather than the bug tracker.

This second patch is required to prevent a rather serious regression where userspace applications reading from stdin can receive EAGAIN when they should not. I will try to link correspondence from the mailing list archives once they are available, but for now if you have access to the linux- console mailing list you can find discussion under the thread "Userspace break? read from STDIN returns EAGAIN if tty is "touched"". I would appreciate it if this could be examined soon as it is a regression on userspace.
