When Olympus camera D-540 Zoom is attached, umass causes Fatal Trap 12. This did not occur with some previous release, which worked perfectly, presented camera as a da device which could be mounted as a FAT (msdos) file system. Fix: I need to know how far back I need to downgrade to get to a pre-broken umass. How-To-Repeat: Happens every time with custom kernel (omitting umass, umass loaded manually after boot), with umass loaded from loader.conf, and with GENERIC kernel.
