FreeBSD radagast.usermode.org 7.1-STABLE FreeBSD 7.1-STABLE #1: Sun Feb 15 14:58:30 PST 2009 david@radagast.usermode.org:/usr/obj/usr/src/sys/RADAGAST i386
>Description:
FreeBSD page faults and panics when connecting an Olympus C740 camera. This happens every time on two separate systems with 7.1-STABLE. I have had this camera a few years, and this is new behavior. It was definitely not doing this the last time I connected the camera in November with 7.0-RELEASE.
