Just to verify, I would assume you've checked the following?: - Bad Cable - May not have appeared until it got loaded - Auto Negotiate Issues (check duplex) - Very common - Force to 10mbps to see if it still happens - For to half duplex in both 10 & 100 mbps - Different physical port on the switch I haven't seen any issues on this list with the em driver, but I may be wrong. I don't have em cards, so other than the above, I can't offer much. -Steve ------------------------------------------------------------------------- Stephen Bader JORSM Internet, Regional Internet Services Systems Administrator 7 Area Codes in Chicagoland and NW Indiana steveb@jorsm.com 100Mbps+ Connectivity, 56K-DS3, V.90, ISDN (219) 322-2180 Quality Service, Affordable Prices http://www.jorsm.com Serving Gov, Biz, Indivds Since 1995 ------------------------------------------------------------------------- On Mon, 5 Jan 2004, Clint Gilders wrote: > Hi > > I'm seeing a lot of the error messages below on a dual Xeon 2.5 Ghz running 4.9-STABLE > built on Wed Nov 26 2003.
