Check /sys/bus/pci/drivers/r8169/unbind. Echoing, e.g., "0000:05:00.0" to that file will unbind the second adapter from the driver, allowing the RTnet driver to pick it up (on insmod or via "echo 0000:05:00.0 > /sys/bus/pci/drivers/rt_r8169/bind"). > > 2.

Check what dmesg reports, check /proc/rtnet/devices. Does /dev/rtnet exist when you want to call rtifconfig? Jan
