It looked perhaps like the problem started on bootup. I saw that
free_irq_vector() was called for the vector assigned to the second
function, right after e1000 claimed the first function on the device.
The network using the first function on the device was actually a little
flaky while dom0 was running too.

Yep, see below.

No, it only occurs if Xen calls free_irq_vector(), so I suspect the
NaT is just the result of something bad happening much earlier. Vector
54 in the below output is the one that gets freed. Thanks,
