I am interested in to see if you have actual test case and more importantly test data that shows that kernel and device indexes are not synchronized any more.Well, it's not with an actual physical device, but with the kvm emulation.
BTW, it also happens easily when request_irq takes some time to complete: since we enable E1000_TCTL_EN before that, the card can have time to fill the ring before irqs are processed.
