Here's the dmesg after an update to 5.0_RC2 (from 4.0), a reboot
with the Generic kernel only (no new userland, yet) and the
relevant parts shown. The second drive does not have a NetBSD
disklabel on it for now. I'll trim the kernel config, do some
probing, sort some of the mess out and get back to you.
