Michael,
I suspect that your p80 ring has the classic data-dependent problem.
You can test it by sending files or pings through the ring that have
the data pattern hex 33, or hex EE, or any of a few others.
With anonymous ftp to jade.berkeley.edu you can get two programs that
may help you detect where the failing component is. The ping.c and
netout.c programs in the pub directory there both take an argument
to specify a data pattern to fill your packets with.
Ping tests the entire ring, while netout sends data to the TCP
discard port on the remote host and so you can use it to exercise
discreet individual segments.
Proteon Customer Service should be able to help you with this, but
if you like you can call me and I'll be happy to discuss it as well.
