There is a new option since rev. 4043 called XENO_FASTSEM. It is set by 
default for x86_32. Have a look at your kernel config file and search 
for that term. Please make sure that you build your xenomai-patched 
kernel and you userland libs and applications with the same revision of 
xenomai and don't forget to install them all on your target.

BTW, for which architecture are you building xenomai?
