Yes, I have tried different cables, even different physical ports (although same type of port). There was a bug filed against 6.1 for the bge interfaces that maybe related, although the bug indicated absolutely no network conductivity. There was a patch released and I'm trying to recompile with that patch. I must admit I'm having a hard time figuring out how to apply the patch but once I get past that hurdle I'll see what happens. If I can't ge the bge interface working my next best solution will be to just install another card in one of the pci slots and use that instead. Ideally, I would upgrade to 6.2 but cpanel won't support 6.2 so I'm stuck on 6.1 for the time being.
