Sorry, didn't realize it was a warning BT. The system continues on without an
oops, but now that I realize that the BT is just a warning I realize that it
never crashed in the first place for my hardware with the 4.8.13 kernel. It
only does the the same warning, not the same Oops. Please disregard my tests
then since I couldn't reproduce the same Oops.
