duh. it helps to read.. > By the way, "Heisenspike" is a great turn of phrase...made me laugh. Unfortunately, it wasnt - it reappeared. for the the very determined, there are xenomai debs with ipipe tracing enabled here: wget http://static.mah.priv.at/public/xenomai-debs/linux-image-3.2.21-xenomaiipipetrace+_0.2_i386.deb wget http://static.mah.priv.at/public/xenomai-debs/linux-headers-3.2.21-xenomaiipipetrace+_0.2_i386.deb dpkg -i linux-image-3.2.21-xenomaiipipetrace+_0.2_i386.deb lucid doesnt have the libtinfo5 package, so it needs a bit of force to install dpkg --ignore-depends=libtinfo5 -i linux-headers-3.2.21-xenomaiipipetrace+_0.2_i386.deb http://www.xenomai.org/index.php/I-pipe:Tracer I do get traces at new latency maximums.
