The board is a Supermicro X7DBP-i: > <http://www.supermicro.com/products/motherboard/xeon1333/5000P/X7DBP-i.cfm>; I'm wondering if the IPMI add-on is what's doing it. However, the IPMI cards compatible with the X7DBP all have a dedicated NIC (versus piggybacking on top of the existing mainboards' NICs, which almost always causes problems of the mysterious sort). I'm not sure, but I don't think em0 will be that NIC. Both you and George have boards that use the 82563EB. jv@ will have to help with this one. I wonder if it's a BIOS bug of some kind, where something on the NIC isn't getting reset by the BIOS on a soft boot... -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
