My 5th generation ipod works fine. the 6th gen ipod can be used just like the 5th gen, in that I can mount it as a USB disk. I can write files to it, I can use any of the ipod music software, etc. However, when I camcontrol eject it, it reports success. The problem comes when I actually physically disconnect the unit.

After which, the spam stops, and the following is logged: Nov 17 02:05:52 Laptop kernel: umass0: BBB bulk-out clear stall failed, IOERROR Nov 17 02:05:54 Laptop kernel: umass0: at uhub4 port 3 (addr 2) disconnected Nov 17 02:05:54 Laptop kernel: (da0:umass-sim0:0:0:0): lost device Nov 17 02:05:54 Laptop kernel: (da0:umass-sim0:0:0:0): removing device entry Nov 17 02:05:54 Laptop kernel: GEOM_LABEL: Label msdosfs/IPOD removed.

Watch your logs grow to insane sizes. Plug in another USB device (or unplug one) and watch it stop. I'm not sure if this is a usb problem, or a geom problem. but the above *does not occur* when using a 5th generation ipod. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
