Scott Testerman, the next step is to fully commit bisect from kernel
4.7.10 to 4.8 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?
Please note, finding adjacent kernel versions, or providing a commit
from a kernel version bisect is not fully commit bisecting.
Also, the kernel release names are irrelevant for the purposes of
bisecting.
It is most helpful that after the fix commit (not kernel version) has
been identified, you then mark this report Status Confirmed.
Thank you for your help.
