At least both my NetBSD and OpenBSD test images survive a casual boot test here with latest git. I was just trying OpenBSD/sparc64 with 8.2 recently and found hme(4) does not work. I tried with the NE2k driver as I remember adding the driver to the OpenBSD kernel before an hme driver existed and it sort of worked, but there were still issues. I'll re-test with 9 now and see what happens. Thanks for the update: my local tests for SPARC changes are boot tests, so it's entirely possible I could miss an issue with the hme device. Feel free to open a GitLab issue with the relevant information and I'll take a look as time allows. ATB, Mark.

Yeah, I don't believe that has been true about NetBSD/OpenBSD for quite some time :) Please do keep the wording about Solaris since I get asked that often (and it's a task that will be quite difficult and time-consuming to do).
