Hello Daniel, I use version 2.6.22.1-rt4, see the following link for LTT compatibility http://ltt.polymtl.ca/svn/ltt/branches/poly/doc/developer/lttng-lttv-compatibility.html I have used LTT on both i386 an on a PowerPC (MPC8555) architecture. It is a great help in understanding real-time behaviour.
