Yup!

That didn't work for me.

Thanks for the link!

I was able to add "pcie_aspm=off" as a kernel parameter.  Now, things
seem to work again.  We'll see how long this lasts before something
else breaks.  :)

As a side note, the NIC doesn't properly activate on boot.  I get a
message saying that there is no link present, check cable.  A simple
"ifup eth0" gets packets moving again.  This NIC seems to leave much
to be desired.  :)
