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

[NancyHsu]

Please take a look with #41.
All the upstream kernel (mainline) we have tested (4.9, 4.8, 4.4.40, 4.4.35 and 4.4.44) are fine.
The two Ubuntu kernels 4.4.0-59 (based on upstream 4.4.35) and 4.4.0-64 (based on upstream 4.4.44) the bug can be reproduced. 
Finally we test kernel 4.4.0-20 the bug can also be reproduced.
