This sounds like busybox is just triggering a kernel issue. Maybe we are
leaking some lock into application context. Are there any special
(RT-)drivers running? Does this already happen with only I-pipe applied
and enabled, but not Xenomai? Please try to describe your scenario
precisely (including .config) so that someone with a similar setup can
try to reproduce it.
