I've received two replies, which together point the way to a solution.

Thanks to David.Miner@East.Sun.COM (Dave Miner) and Casper Dik
<>. Thanks also to any others whose replies
cross in the mail with this summary.

David suggested seeing if something was wrong/missing in /dev and
doing 'b -r' on the system. Casper reminded me about truss(1),
which when run with 'ps' generated a massively recursive reference
to /dev/ This dev file turned out to be a symlink pointing
nowhere. I looked at another Solaris 2.1 system and found that
/dev/ is a symlink to /dev/term/b and when I recreated this
link, the ps and w problems went away, without a reboot.

Casper stated that the panic I experienced had nothing to do
with the other problems, and told me about patch #'s 100884-07
and 100819-01. (Neither of these patches is mentioned in the
12/92 release of SunSolve, the latest I have--has a later version
shipped yet?) David also mentioned a Solaris 2.1 patch, but
said he'd upgraded to 2.2 and didn't recall the patch number.
