Hi Jan,
When doing a correct start i get:

dmegs just says the same. As soon as I stop the rtnet service on the slave, the
master is spamming TDMA errors. But that makes sense.
Checking through /var/log/messages I found in the error case:
Oct 26 15:00:07 nfs1-webcam daemon.err udevd[1107]: worker [1268] unexpectedly
returned with status 0x0100
Oct 26 15:00:13 nfs1-webcam daemon.err udevd[1107]: worker [1268] failed while
handling '/devices/virtual/net/vnic0'
Oct 26 15:00:23 nfs1-webcam user.warn kernel: TDMA: Failed to transmit sync mit
sync frame!
Currently, there is no further access to another host. Will try to get one next
week and check the NICs there.
Cheers
