nfsroot with netbsd-8

[Paul Ripke <stix%stix.id.au@localhost>]

I tried upgrading a little nfsroot sparc box to netbsd-8, and have
run into an interesting problem:

root on le0
nfs_boot: trying DHCP/BOOTP
nfs_boot: DHCP next-server: 192.168.0.1
nfs_boot: my_name=orac
nfs_boot: my_domain=private
nfs_boot: my_addr=192.168.0.12
nfs_boot: my_mask=255.255.255.0
nfs_boot: gateway=192.168.0.1
root on 192.168.0.1:/home/orac
root file system type: nfs
kern.module.path=/stand/sparc/8.0/modules
warning: lookup /dev/console: error 13
panic: init died (signal 6, exit 5)

So, the kernel loads successfully via nfs, configures le0 fine, even
loads /sbin/init - but fails on /dev/console. And the /dev/console looks
fine:

crw-------  1 root  wheel  0, 0 Dec 29  2016 /home/orac/dev/console

Looking at the nfs traffic during the boot, I see a permission denied
for an odd major/minor filehandle, which I think is the lookup on
/dev/console. Anyone have any ideas what's going on? fwiw, the server
is amd64, netbsd-7.
