Hm, irqloop is from the irqbench test suite requiring a special setup
and does not make sense on non X86 systems: See

You can find the error codes here:

http://www.xenomai.org/index.php/Resolving_Error_Codes
http://lxr.linux.no/linux/include/asm-generic/errno-base.h
http://lxr.linux.no/linux/include/asm-generic/errno.h

Most likely the corresponding driver modules for timer testing is not
loaded or linked into the kernel.

It's at least a good sign.
