I am not sure if this mail will be delivered properly to that list.


If you will need any other dumps, let me know.

Thanks,

hello,

The information you provided is not nearly enough to get
started {sorry}, please see the developers handbook
for more information
http://www.freebsd.org/doc/en/books/developers-handbook on
how to obtain the proper kernel dump that can be processed
by our developers. Also please consider using ipfw@FreeBSD.org
for this report since it would most likely get better attention
there {special ipfw mailinglist which seems more appropriate}.

Thanks for using FreeBSD!!
