My suggestion is to try it in x86_64 PC. Then you can just use live
linux distro with different kernel versions. If it does not work with
any of these you may have ran into a hw bug sample. If it does work
then you don't need to update your PPC64 kernel but find an
architecture/device speific bug that prevents it from loading.
