[Bug 1646277] Re: Xenial server 16.04.x will have a black screen after PXE installation

[Joseph Salisbury]

It sounds like the upstream 4.4 kernel does not have the bug per
comments #10 and #12.

It appears this bug may be caused by a SAUCE patch that is not in the
upstream kernel.  To confirm that, can you test the upstream 4.4.44
kernel, which is what 4.4.0-64.85 is based on?

If the bug does not exist in 4.4.44, we can perform a kernel bisect with
the Ubuntu kernels to find that SAUCE commit that introduced this bug.
