So, are you suggesting that it's worth testing this patch?  I'm on
5.3-STABLE, and I got so pissed off last night with my sk0 interface that I
brought the machine down and disabled the onboard network and installed a
Linksys 100Mbit card.  My board is the ASUS P4P800-SE, but I believe the
interfaces are the same/similar.

My favorite way to hang it was to use gtk-gnutella.  Massive amounts of
small-sized inbound traffic seemed to bring on the hang (the tell-tale
'watchdog timeout' kernel message).
