I hadn't noticed immediately in the ooops, but it is something to do with the Hardware Abstraction Layer Daemon from http://freedesktop.org/Software/hal I can't reproduce it without that daemon loaded either. I wonder if the last accessed sysfs file mentioned in the oops (sda/size) is relevent also.
My exact steps (with hald loaded) are: plug in ipod mount /mnt/ipod unzip -d /mnt/ipod rockbox.zip eject /dev/sda unplug ipod immediately here, the oops prints.
Interestingly after this happens, the system remains at a pretty high level of functioning, and further mounts and unmounts and ejects of the ipod do not cause another oops.
