I started a kernel bisect between Ubuntu-4.15.--32 and Ubuntu-4.15.0-33. The kernel bisect will require testing of about 7-10 test kernels.
I built the first test kernel, up to the following commit: 77a24c313d21e3765b04d90521e9228a9bb6e332 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1792100 Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.
