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/.
