Jack et al, is this normal? I don't see this behaviour on my 8.x systems with em(4) driver 7.0.5, but my systems all use 82573E and 82573L, and don't have MSI-X support. -- | 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.
