Built the 2.6.27.1 kernel and booted under Fedora. Built both OEM 'igb' and 'ixgbe' with DCA enabled, using the native 'dca.ko' and 'ixgbe.ko'.
The latest kernel behaves about the same as the Fedora native kernel: 1) native 'igb' does not work 2) OEM 'igb' works, but only if IntMode=1,1,1,1 3) 'ixgbe' gets MSI rather than MSI-X interrupts My impression is that the device-to-memory DCA feature I'm interested in will work only when MSI-X interrupts are enabled, so it seems that I can not evaluate this new feature as of yet.
