From what you're telling us, it really looks like a kernel problem
(either a configuration one, or a real problem in the kernel code).
Since you're able to use a recent version of the kernel (3.10), it
means that you can easily benefit from support from the kernel
community. I would therefore recommend you to get in touch with the
PowerPC kernel developers doing the support for this board/SoC and
asking the question there.

Best regards,

Thomas
