Running 2.6.9-rc1-mm4 with the above patch.
I'm a bit unsure of the timing, but at some point I got this either
before or during the transfer I set up to get some Tx activity, a
repeated wget of a 35M file.
irq 10: nobody cared!

Disabling IRQ #10
I killed the transfer and started X, getting this immediately:
irq 16: nobody cared!

Disabling IRQ #16
This also happened during the originally-reported incident, which I
forgot to mention. Both times, downing and then upping the interface
resulted in what seemed like a solid hang, although possibly it was
just X.
I rebooted and started X again, and again got the above. If I boot
with acpi=noirq, I don't get that message upon starting X. Here's
/proc/interrupts before and after starting X, without passing
acpi=noirq:

I don't know if this is significant, but with acpi=noirq,
/proc/interrupts looks like this:
CPU0 CPU1

eth2 being the 8169.
Unfortunately after tonight I won't have access to this machine until
Friday evening. I'll grab the netdev patchset and try those next.
