In my case, to the contrary, a Windows machine does positively influence the FreeBSD machines. Look: - One switch connected to bge3 on both FreeBSD machines, no other connections. - The machines cannot ping each other. - Hook up a Windows machine that basically does nothing at all to another port of the switch. - As a result, the machines can now ping each other. - Disconnect the Windows machine. - The machines continue working normally. > (Symptom is that the NIC reports the link as up (PCS synched) but > no traffic can be exchanged.) > This message is from revision 1.71 of the bge driver.

So I would guess that it is already included in 6.2!? > hm, what happens if you disable ARP? > ifconfig intX -arp > and use static ARP? Point taken, this does not fix it. On the other hand, forcing the link speed likewise does not fix the problem, so I don't think it is an auto negotiation problem, either. In the meantime, I have found out that the affected interfaces show similar problems on Linux (Debian Etch). I'm starting to get the impression that this is a hardware issue. There was a bug reported for the BIOS of this xSeries 346 that leads to "PCI configuration errors" resulting in "SCO Unixware not picking up network connections". I flashed the updated BIOS, but to no avail.
