The following reply was made to PR kern/127699; it has been noted by GNATS. From: Volker Werth <vwe@freebsd.org> To: Wouter Snels <nospam@ofloo.net> Cc: bug-followup@freebsd.org Subject: Re: kern/127699: [panic] Fatal trap 12: page fault while in kernel mode Date: Sun, 05 Oct 2008 00:38:38 +0200 This is a multi-part message in MIME format. --------------030100040509040701090805 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Wouter, please run the attached script and file a followup to the PR (leave bug-followup@ in CC). The script will rebuild the environment of your crashed kernel (load your old kernel from /boot/kernel.old and load kld's into address space), then will give us the backtrace and some code snippets of the faulting code. I've included three instruction addresses picked from your various panic messages. At least two of them are related to if_stf.ko (judged from their code addresses).
