Yes, it panics on mount.
Sequence:
0. usbd running
1. Connect camera - camera is detected & identified
additinally, camcontrol works, i.e. rescan detects proper
SCSI device(s)
2. (try) mounting it - immediate panic & reboot, panic is a
divide by zero someplace
Previous email indicated that it appears to be a problem
with the "geometry" of the device. It gets a zero
someplace in "CHS"(?), thus the divide by zero. <shrug>
