One of these days I'll try it I'm sure. Vivek: I'd be interested in your experiences w/6.0. Would you mind testing the onboard bge nics at the kind of loads that was causing them to puke under 5.4? I've got same system and as of yet not encountered issues w/ the onboard bge nics. The machine is also at the latest BIOS, however, so that may contribute as well.
