Thanks very much for your testing and detailed problem report. This problem actually isn't in e1000. Can you try the attached patch, please? I thought I'd seen this patch before, but it doesn't seem to be in -mm yet.
Make assign_irq_vector() non-__init always (it's called from io_apic_set_pci_routing(), which is used in the pci_enable_device() path).
