Hello, I've sent some bug reports about this, but maybe that wasn't the best place to post it. When upgrading to a snapshot with sysupgrade and rebooting, the display hangs as openbsd loads wdisplay0, and xenodm nor X will start. I don't think wdisplay loads at all. This happens on amd64 with the multiprocessor kernel, but not with the single processor one. I did not notice anything out of the ordinary during the upgrade. Anyone might be able to help?
Latest bug report with Xorg.log, dmesg, and acpi is here: https://marc.info/?l=openbsd-bugs&m=160575016004118&w=2
