 >From the image: the crash happens at:
 
 intr_disestablish()+0x17
 ixgbe_free_pciintr_resources()+0x3f
 ixgbe_attach()+0x24a
 
 The msix interrupt queue disestablish is not protected with if
 (sc->osdep.ihs[i] != NULL) like the others a few lines below, so if we
 have not been sucessfully through ixgbe_allocate_msix() this might
 crash (we go to err_out in ixgbe.c: 7048 and then call
 ixgbe_free_pciintr_resources).
