I built a test kernel with commit cd8dd032f61abeb08d2c03bab4968a9de231a1be. This test kernel also had commit 3d8bba9535a applied first.
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1769027 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-image-unsigned, linux-modules and linux-modules-extra .deb packages.
