Um... I can't replicate anymore. The bug triggered reliably on Arch for me on
4.15.1, but Arch has since updated to 4.15.3 and this has... somehow caused the
card to start recognizing the HDMI card on boot (in non-DC mode when I just
booted it, twice). I'd been using the 4.14 series of LTS kernels in the
meantime, and none of the changes had seemed to indicate anything that would
fix it in the 4.15.x point releases...
Good work, I guess. Sorry about the wasted time, if it occurs again (it
triggered a bunch for me on a few days after 4.15.x came out) I'll post the
logs.
