So the master is configured for precisely this one slave? > suspected it depends on the network controller “Intel pro/1000”.

Any interrupts arriving on the RT NICs on both sides? Have you checked for IRQ conflicts on the master side? Do both systems work over a longer time (a few dozens of packets) without using RTmac/RTcfg, just directly rtpinging? Jan
