first off, thank you so much for your work on all this, it's been a
great pleasure to discover everything you've done to support device

I have a Gigabyte GA-Z170-HD3P that exhibits the same issue that Nick's
system has (I checked with lspci -xxxxs 1c). I want to follow your
recommendation to report this to the vendor, but I do not know how to
describe the issue in a way that they can understand what's going on and
hopefully work on a fix. I guess making more high-quality bugreports
about this will have an actual chance of getting it fixed, rather than
just a single person complaining.

Thank you
