Yes, please. I assume your system is otherwise stable (without
Xenomai/I-pipe enabled).

It would also be nice if you could retry over 2.6.31.x with latest ipipe
patch. And try to switch on CONFIG_IPIPE_DEBUG_TRACE_MCOUNT. That may
give a function back-trace on oops, maybe providing more pointers where
we come from (but it may also make the issue disappear).
