System: NetBSD 9.99.52 NetBSD 9.99.52 (GETHSEMANE) #31: Wed Apr 1 15:57:13 CEST 2020 macppc
Architecture: powerpc
Machine: macppc

I tried (as root):

	ofctl -p /rom/boot-rom/model

and the command hang - probably with kernel lock held or something, as most
other things stopped working (but getty on consol still offered a new login
prompt, but login in did not work)
