Sporadic or deterministic bug? Specifically in case of the latter I=20
would be interested in your .config.

Unless the slowdown papers over the actual issue, letting the ipipe=20
tracer run, so that it reports a nice backtrace on the BUG, may help us=20
tracking down the point where irq_enable is missing (also in=20
non-Xenomai/Ipipe code).
