It appears that I hit upon a fluke. The machine finally hung again after
a few days of use, and I found after the hard reset that the interrupt
problem was back. So, I'm back to running sans apic for now.

Actually, after re-reading all the previous threads again, it doesn't
appear that any of the recent fixes to em had anything to do with the
shared irq issues anyhow. I'm now left feeling a bit confused, but that
may just be due to lack of sleep.
