--3MwIy2ne0vdjdPXF Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I finally(!) got around to enabling crash dumps on the primary machine here at the house ... and managed to make use of it (unfortunately). I've copied the relevant files (both those from /var/crash and dmesg.boot) so they should be visibale at <http://www.catwhisker.org/~david/FreeBSD/panic_24Dec2012/>; (though only the dmesg.boot, core.text.0, & info.0 files should be fetchable for now). [I'll make the vmcore.0 available to individuals who wish to work on the problem; please contact me to arrange this.] Here's a bit of information excerpted from core.text.0: Mon Dec 24 11:16:04 PST 2012 FreeBSD albert.catwhisker.org 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #434 24= 4582M: Sat Dec 22 05:06:29 PST 2012 root@freebeast.catwhisker.org:/usr/= obj/usr/src/sys/ALBERT i386 Note that while the version string says "244582M": * Userland was at r244608. * The "Modification" was merely a change to src/sys/newvers.sh to re-factor the extraction of the version string. panic: page fault Fatal trap 12: page fault while in kernel mode cpuid =3D 0;
