As I mentioned in my previous note, I've finally started playing with
the next68k port.  I just now had occasion to reboot the box (same
kernel as last time I booted), died.  Here's what I see
(ten-finger transcription, but I don't *think* there are any typos):

NetBSD 1.4 (GENERIC) #0: Fri Aug 13 17:59:97 PDT 1999
NeXT/MC68040 CPU+MMU+FPU, 4k on-chip physical I/D caches
real mem  = 16769024
panic: pmap_enter_ptpage: PT page not entered
Stopped in  at  _Debugger+0x6:  unlk    a6

_Debugger(2704,1,419f000,0,157c84) + 6

_pmap_enter_ptpage(100708,1400000) + 50c
_pmap_enter(100708,1400000,42c8000,3,1) + b8
_cpu_startup(17d54,e63b4,4001000,0,d952c) + 16e
_main(2663e,15b000,0,1000,1000) + 38

Two successive reboot attempts failed with the same panic at apparently
the same place (I didn't check the stack trace).  But when I did the
ctl-alt-* hard-reset, let it try to boot and fail because it tries to
boot en() instead of en()/netbsd, and then type en()/netbsd at the
boot: prompt, it came up normally.

Worth investigating, or should I ignore this until/unless it happens
again with -current?  I'm preparing to move to -current....
