If I had to put money on one of the left-over commits, I'd go with

commit 3d42f1ddc47a69c0ce155f9f30d764c4d689a5fa Author: Aaron Ma aaron.ma@canonical.com Date: Sat Sep 1 02:20:00 2018 +0800

vgaarb: Keep adding VGA device in queue

If failed to find the deivice owning the boot framebuffer,
try to use the first VGA device instead of the last one.

Usually the 1st device is integrated GPU who owns the boot framebuffer.

Which seems to change the vgaarb logic wrt which device is the primary.

Thanks a lot for the hint. I am looking forward to the git bisect result.
