Did you try enabling the pipeline debug options, like
CONFIG_IPIPE_DEBUG_CONTEXT and CONFIG_IPIPE_DEBUG_INTERNAL?

Xenomai runs on Emerson's mvme7100 powered by a 8641D, but FSL eval
boards which are known to work with Xenomai are uniprocessor only so

known to work, but I can't tell for any other hw.
