Comment 9 for bug 1794477

I can build you kernels for the bisect. You test the kernel and post back if it has the bug or not. Then I will build the next kernel based on your results. Repeat.

To start a bisect, we first need to identify the last good kernel version and the first bad one. Can you test the following kernels:

4.15.0-29: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/ppa/+build/15137612
4.17.0-4: https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/bootstrap/+build/15068818
