I've installed an Intel Pro/100 adapter in the Dell PowerEdge 2650. This is an Intel 82550 chipset. The packet loss problem is completely gone when using this NIC in the server, so it is definitely related to the bge driver and this chipset BCM5703 or something else in the server. I'm going to try and isolate which major release this problem appeared. Maybe this will help isolate the change that is causing this issue for me. -- Vinny Abello Network Engineer [EMAIL PROTECTED] (973)940-6100 PGP Key Fingerprint: 3BC5 9A48 FC78 03D3 82E0 E935 5325 FBCB 0100 977A Tellurian Networks - The Ultimate Internet Connection http://www.tellurian.com (888)TELLURIAN "Courage is resistance to fear, mastery of fear - not absence of fear" -- Mark Twain _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
