Just found this bug and I'm impacted with an iPod nano G3. 10.10 seems to work fine mounting the drive but I can't get my audio (alsa) to play nice. In 11.04 the audio works quite well but the ipod with hfs+ doesn't mount.

Current installed kernel:
Kernel Linux 2.6.38-10-generic (11.04 natty)
iPod plugged in at boot or later gives the following error in a pop-up:

Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdc2,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

dmesg | tail output:

The iPod is a 4gb model and Disk utility shows two partitions
/dev/sdc1 of 254 kB (253,952 bytes) of Unknown volume with Apple Partition Map
and
/dev/sdc2 of 3.9GB (3891,793,920 bytes) HFS+ of Apple HFS/HFS+Partition.

At the moment I don't have the time to apply the patch of comment #19 or #36.
Should I apply the patch of comment #36 given I have installed Kernel Linux 2.6.38-10-generic?
