I built a test kernel with commit 44de022c4382541cebdd6de4465d1f4f465ff1dd. The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1789653
Can you test this kernel and see if it resolves this bug? Note about installing test kernels: • If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages. • If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.
