Sporadic or deterministic bug? Specifically in case of the latter I
would be interested in your .config.
Unless the slowdown papers over the actual issue, letting the ipipe
tracer run, so that it reports a nice backtrace on the BUG, may help us
tracking down the point where irq_enable is missing (also in
non-Xenomai/Ipipe code).
