ENOSYS would rather be symptomatic of this bug which is ARM-specific:
http://git.xenomai.org/ipipe.git/commit/?h=ipipe-3.10&id=e410a5e77323d53277d625e5dafe166cdcd64afb

OTOH, the patch below fixes a spurious EINTR error within the task 
creation syscall, which may well end up in a lockup:
http://git.xenomai.org/xenomai-2.6.git/commit/?id=589882956280d5cb4fdc181a5fcd5ae1188ab6ed

This is one of the situations where knowing the CPU architecture 
involved would help a lot.
