They are always the most annoying issues. I was looking for something
relatively easy to do, but more importantly, easy to revert :)

Another thought might be to copy the good netbsd-8 machine across to
the problem machine to see if the issues still show (albeit at the
temporary loss of netbsd-9 there :)

Do you have them setup to netboot? Quite a while back I supported a
student(ish) cluster of mixed sparc boxes, some of which had SCSI
drives that failed but could be recovered with a reformat, and with a
spiderport console I had the process pretty much automated to
reformat, reinstall and reconfigure once I manually netbooted (from
eight timezones away at times :)
