[tulip] Thousands of "System Error occured" errors

[Brian Wallis]

I have a couple of 90MHz Pentium machines with Tulip based cards in
them and when booted with readhat 6.2 installed I keep getting error
messages of the form "System Error occured" whenever there is lan
access. The lan access is working but very slow (due mainly I think to 
the logging of the thousands of error messages)

There are no other error messages to be found so I have no idea what
is actually going wrong.

The PCs are Siemens PCD 5H with PCI ethernet cards that have a chip
with a blue top and ZNYX printed on them. Output from tulip-diag is as 
follows.
