No. The information you supply isn't enough.
If you only had this problem once, we'll never find out. If it
happens more frequently, you'll need the following:
1. A kernel with debugging symbols. You build a debug kernel like
this:
# cd /usr/src/sys/i386/conf
# config -g MYKERNEL (substitute the name
of your config file,
GENERIC by default)
# cd ../../compile/MYKERNEL
# make depend
# make
# cp kernel kernel.debug (these two lines are
# strip -g kernel new)
# make install
2. Ensure that dumping is enabled. You should have a line line this
in your /etc/rc.conf:
dumpdev=/dev/wd0b
Substitute the name of your swap partition for /dev/wd0b.
3. Ensure you have a directory /var/crash, and that the file system
has enough space for a dump and a kernel (about 12 MB more than
your memory size).
If you have another panic, you should then get a useful dump in
/var/crash. There's a section about debugging it in the online
handbook. If you still have trouble, ask us again.
