--V2Kn1ZfDiPlyQ6Qk Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable I was minding my own business in a staff meeting this afternoon, and my laptop rebooted; seems it got a panic. I've copied the core.txt.0 file to <http://www.catwhisker.org/~david/FreeBSD/stable_10/>, along with a verbose dmesg.boot from this morning and output of "pciconf -l -v". This was running: FreeBSD localhost 10.2-STABLE FreeBSD 10.2-STABLE #122 r286878M/286880:100= 2500: Tue Aug 18 04:06:33 PDT 2015 root@g1-252.catwhisker.org:/common/S= 1/obj/usr/src/sys/CANARY amd64 Excerpts from core.txt.0: panic: page fault =2E..

() Previous frame inner to this frame (corrupt stack?) Current language: auto; currently minimal (kgdb)=20 Physical 802.11 hardware is iwn(4). I can copy the vmcore.0 file itself after I get home -- it's ~625MB, and I'd rather not try to get that through over a WAN before I need to catch the shuttle to get home. :-} Peace, david --=20 David H.
