#
# GENERIC -- Generic kernel configuration file for FreeBSD/i386
#
# For more information on this file, please read the handbook section on
# Kernel Configuration Files:
#
# http://www.FreeBSD.org/handbook/kernelconfig-config.html
#
# The handbook is also available locally in /usr/share/doc/handbook
# if you've installed the doc distribution, otherwise always see the
# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the
# latest information.
#
# An exhaustive list of options and more detailed explanations of the
# device lines is also present in the ./LINT configuration file. If you are
# in doubt as to the purpose or necessity of a line, check first in LINT.

>How-To-Repeat:
In the host run the program for discover IP addreses and ARP addresses
and Windows host names (samba)our network. Sometimes system crash ( ~ 1,2 times in week).
>Fix:
I do not know.
This error was in my FreeBSD v3.3 stable (see the bugs Problem Report kern/20671 at 16 aug. 2000)
