--- Comment #43 from Brian Ward <bward at redhat.com> ---
Hello all,

I tested from latest Fedora kernel and still reproduced my problem.
4.19.12-301.fc29.x86_64

I built from latest drm-tip 4.20 as of 1/2 and could not reproduce the problem.
c6a0276a5007c01c64a8a80552b78c115e8a0dae

It would be great if anyone knows how to identify the code that I could use to
patch a 4.19 and/or 4.18 kernel to make this work correctly.  Any hints would
be appreciated.
