 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.
