I also started a kernel bisect between Ubuntu-4.15.0-38 and Ubuntu-4.15.0-39. The kernel bisect will require testing of about 7-10 test kernels. I built the first test kernel, up to the following commit: 125291b1852e43501135f787adf03fa590e33f59 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1803392 If -proposed still exhibits the bug, 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.

Nothing sticks out in that range of commits. There is nothing atheros related. Before starting a bisect, can you confirm -proposed does not already fix the bug?
