Comment 49 for bug 734883

apologies if i should be opening a new bug report instead of updating this one.

I am experiencing the same problem on Oneiric with kernel version 3.1.0-0301rc4-generic. Which is to say, my iPod doesn't mount, and the system reports "wrong fs type, bad option, bad superblock" when the system attemps to auto-mount.
This is a stock kernel, not customised in any way, and is installed by synaptic during the upgrade.

In addition, I am getting kernel panics when plugging in the iPod. Doing less /proc/kmsg produced the following:

Hope this helps, and I will refile if this isn't the correct place for this report.
