Okay.  I've learned a little more about this.  If I power down the
laptop and leave it off for a few minutes then power it up, login and
ifconfig re0 ... it panics.  I got a core dump with 'call dumpsys',
'panic' didn't work.  Next I entered 'reset' at the db> prompt.  I
logged in again and ifconfig re0 ... and it panics again.  Same db>
stuff as before and reset.  This time everything hangs after ifconfig
re0 ....  Power cycle and then I can ifconfig re0 ... and pass
traffic.  I did this all again (i.e. 2 panics, a hang, then open
sesame) to verify the process.  I have uploaded the kernel and vmcore
files for the panics onto leaf.dragonflybsd.org:/home/josepht/crash/.
Two panics are in the same place (outl), so I suspect this may be the
effect of writing to some reserved hardware registers.  Please test
following patch:
