I have some errands to run; should be back within about 1.5 hrs., but
will be quite willing to poke  hack around to see what's up after that
time.

Cheers,

Ahhh... that would seem to have been merely fallout from the upgrade
process I used.  A subsequent reboot worked fine:

freebeast(5.0-C)[1] uname -a
FreeBSD freebeast.catwhisker.org 5.0-CURRENT FreeBSD 5.0-CURRENT #84: Wed Feb 20 
07:20:46 PST 2002 
[EMAIL PROTECTED]:/common/S4/obj/usr/src/sys/FREEBEAST  i386
freebeast(5.0-C)[2] 

and I didn't even have the above-referenced panic at all on my laptop:

g1-7(5.0-C)[1] uname -a
FreeBSD g1-7.catwhisker.org 5.0-CURRENT FreeBSD 5.0-CURRENT #3: Wed Feb 20 09:13:13 
PST 2002 [EMAIL PROTECTED]:/common/S3/obj/usr/src/sys/LAPTOP_30W_NC  i386
g1-7(5.0-C)[2] 


So... move along, folks; nothing to see here  Sorry for the noise.

Cheers,
