G'day once more. I can now confirm that things worked as expected with: kernel-default-4.12.14-lp151.25.3.x86_64 I verified this by making a tarball of the kernel files from the snapshot before updating. So works in .3 breaks in kernel-default-4.12.14-lp151.25.4.x86_64 Can we get a diff of these for the upstream report? Or maybe just for my own exepriments?
