You're welcome Putatieve, thanks for testing the Xenial 4.4.0-143 version! And you're right, we will have a fix for Xenial-HWE - as soon it is available, you will observe a new message from Brad Figg here, this time adding a tag "verification-needed-bionic". And then, likely the version for Xenial-HWE will be ready to test.
Notice the "likely" word above: happens that the build process is usually parallel, with Bionic 4.15 and Xenial 4.15~16.04 at same time; but there are small code changes (mostly toolchain related) between Bionic 4.15 and Xenial-HWE, so it may happen that Bionic version is ready before Xenial-HWE. It's likely to be at same time (or with some hours of difference) though. If you're interested in more knowledge about Ubuntu kernel cycles, I'd like to suggest you this interesting wiki page: https://wiki.ubuntu.com/Kernel/FAQ#Kernel.2FSupport.Ubuntu_Kernel_Release_Schedule You can check the releases and also, how the HWE works (18.04 kernel 4.15 is present as a long-term supported HWE kernel for 16.04.5 version; same relation we observe between 16.04 and 14.04.5). Feel free to expose any remaining questions you have - also, your testing when the 4.15 version gets released to -proposed is much appreciated!

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.
