Hi!
I do not know if you have solved this but reading here:
http://www.alexonlinux.com/smp-affinity-and-proper-interrupt-handling-in-lin...
It is written that:
"So if on your system CPU0 handles all interrupts by default, this probably means that APIC configured ambiguously."
So maybe it is nothing wrong with e1000e drivers/cards but with APIC configuration?

Hi!
And:
There’s a kernel configuration option that stands in our way and once removed you will get similar situation with probably any kernel newer than 2.6.10. The option is CONFIG_HOTPLUG_CPU. It adds support for hotplugable CPUs. It appears that having this option off, makes kernel configure APIC properly.
