Hi all, Can someone shed some light on what might be causing the message: protocol 0008 is buggy, dev eth1 One interesting fact about it is, that it only seems to appear when the interface runs in promiscuous mode. The problem has happened with two different ethernet network cards as eth1: ne2k-pci and 3c509. eth0 is an fddi interface using ethernet encapsulation eth1 is currently a 3c509 10 MBit/s ISA card which exhibits the problem The box is a Pentium-100 which routes between both interfaces via packet forwarding. The kernel is 2.4.16 with a proprietary fddi driver as module.
