Hmmm, so am I correct in understanding that this root is remote, so its really coming in over the the em driver? I remember someone having problems with remote boot/mounts at some point, think it was Sam, but we resolved it, and I don't remember what it was, but it had nothing to do with MSI/X. This is pretty odd, I've never run into anything like it so far. Anyone else with ideas or suggestions? Regards, Jack
