>Description:

I'm running 5.0-CURRENT with a kernel built from sources cvsupped at
around 11:27 UTC 2000-04-06, with a couple of small patches from Soren
Schmidt (needed so my IDE CD-RW drive will work).  When I run "sysctl -a"
as an ordinary user, my system panics. My /sbin/sysctl is out of date
(from around March 6th) but this seems like something a hostile user could
take advantage of.  My kernel configuration is at
http://jpj.net/~trevor/freebsd/FREEBASE50b.gz .

>How-To-Repeat:

% /sbin/sysctl -a

>Fix:

unknown
