Hmm, in this case we might need your help to do a kernel bisection to figure out which commit is causing this issue:
First, install git and clone the Bionic kernel tree: $ git clone git://kernel.ubuntu.com/ubuntu/ubuntu-bionic.git Then install the tools the you need to build a kernel. $ sudo apt build-dep linux Here we go! $ cd ubuntu-bionic $ git bisect start $ git bisect good Ubuntu-4.15.0-47.50 $ git bisect bad Ubuntu-4.15.0-48.51 In this case you will get roughly 7 commits to try $ make localmodconfig $ make -j`nproc` deb-pkg Install the newly built kernel (deb file) and reboot. If the issue still happens, go to the ubuntu-bionic directory again and: $ git bisect bad Otherwise: $ git bisect good And build the kernel again: $ make -j`nproc` deb-pkg Repeat until you find the commit that causes the regression.
