Thanks for clearing that up for me. > Yours is a different revision, but I suspect your problem isn't with > the NIC.

It worked fine for me for years now, and the only machine that has these sort of problems is the new one with the vr(4) in it.

Don't know exactly how to test this issue. Let me tell you my config and what I've tested so far. This is a computer inside my home LAN. All the computers in my house are connected, via the switch menitoned above, to an OpenBSD server. The NIC is configured via DHCP. It's a common setup. I run OpenBSD exclusively on my machines so I can't test if the NIC works well on another OS (although I know/saw it ran just fine on Windows 2003 Server, the OS that the ex-owner used with this compie). My test have been pretty simple actually: - looking at ifconfig for proper duplex - investigating the server's pf.conf for quirks - ``ping -f''-ing, all went fine 0.00% loss - tcpdump-ing, nothing strange there either - changing the cable and it's position in the switch If you need the output of any tests just ask. Same if additional are required. I'm going to warranty with this mobo today (it's an integrated NIC) due to non NIC related issues (the AGP slot is broken). They'll probably supply me with another mobo. Maybe that will fix this too. Or not. I'll send a new dmesg and notify if anything has changed when I get back. Paul.
