Comment 45 for bug 1792100

If that is the case, we are better off performing a "Reverse" bisect to identify the fix in mainline versus investigating what went wrong in the first regular bisect.

The steps for a reverse bisect are similar, but we first need to find the last "Bad" kernel and the first "Good" kernel. Can you test the following kernels:

v4.19: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.19/
v4.20-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20-rc1
