Hi all, I'm installing xenomai 2.2.5 (kernel 2.6.17.14) on a number of systems (MSI 945P, Intel P4 3Ghz). My kernel runs fine on several other/older systems, but on the new systems there is something going on every 8 seconds. See output of latency test below. What could this be? Is this an SMI effect?
