Jack Vogel of Intel would be able to confirm for sure; CC'ing him here. Could you please provide output from the following commands? * pciconf -lvcb (only include igbX entries, thanks) * sysctl -a | grep msi Thanks. I can't help with the CARP-related issues or other stuff you're experiencing. These issues may all be separate problems, hard to say. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
