I just happened to trip over this report, and at least
one of the lcpci entries shows a Realtek NIC, which
makes me suspicious in light of the report I just
filed at bug #746914. You might want to take a
look at that in case it seems relevant and/or try
the nc | tar pipelines I was using (I haven't yet
tried NFS; I will once my system is stable otherwise).
(Short story is that any amount of I/O was fine
-unless- there was also PCI-bus activity, whereupon
raising the I/O rate had an exponential effect on the
time to failure---again with a "jabbering" lockup in which
the receiving machine was continuously transmitting
on its Ethernet but was otherwise hung or nearly hung,
which also sounds somewhat like the "ghost traffic"
someone reported above, maybe.)

I have a replacement (non-Realtek) NIC arriving on
Friday and will update the report once I can test it.
