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? -- Sebastian
