auto-mounting HFS+ volume fails and kernel panics

[dumi]

Using Oneiric with kernel version 3.1.0-0301rc4-generic, my iPod doesn't mount when the system attempts an auto-mount. The system reports "wrong fs type, bad option, bad superblock" when attempting auto-mount.

In addition, the kernel panics immediately or a some seconds afterwards. This is a stock kernel, not customised in any way, and is installed by synaptic during the upgrade from Natty Narwahal (Ubuntu 2.6.38-11.50-generic)

Here is output from /var/log/kern.log:

[Seth Forshee (sforshee)]

A fix for the panic has already been applied (bug 854987), it just hasn't been released yet.

There are some patches upstream related to mounting large HFS+ volumes, which will probably fix your "filesystem size too large" errors. I'll build a kernel with all of these fixes applied for you to test.

[dumi (dumisizwe)]

sforshee: Thanks Seth. I'll test as soon as you have the kernel build ready.

[Seth Forshee (sforshee)]

dumi: The build is available at:

http://people.canonical.com/~sforshee/lp857509/linux-3.0.0-11.18~lp857509v201109231635/

Let me know if it works. Thanks!

[dumi (dumisizwe)]

Seth: That build worked Seth. iPod mounts and is accessible now. If you need any extra info (outputs) let me know. Thanks a lot.

[Seth Forshee (sforshee)]

dumi: I just noticed that the problem you're encountering was actually introduced after the kernel version being used for oneiric. Then I saw that you're reporting this with the with a 3.1.0-rc mainline build.

The mainline builds are for testing purposes only and are not supported, so I'm marking this bug invalid. You should not be seeing the mount failure in oneiric, but if you are please reopen the bug.
