There is a wiki page available that has some information on bisecting: https://wiki.ubuntu.com/Kernel/KernelBisection
If you want to give the bisect a try, you can do that. I can assist with questions. Otherwise, I started a "Reverse" kernel bisect between v4.12 final and v4.13-rc1. The kernel bisect will require testing of about 10-13 test kernels. I built the first test kernel, up to the following commit: e5f76a2e0e84ca2a215ecbf6feae88780d055c56 The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1721856 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.
