I've been having some problems with an Intel EtherExpress 100+ card (which
2.2.6-RELEASE is seeing as a 100B card, fwiw) running in 100 megabit mode,
full duplex, to a Cisco Catalyst 2900XL.  Running tail or grep on a large
(>10mb) file via NFS from another 2.2.6 machine (with an Intel 100+ too)
will simply freeze the tail or grep process, and it won't die.  ps shows
the process in disk wait, even though other operations on the mount will
be fine.
  
When I replace the Cisco with a 10 megabit hub, the cards drop to 10
megabit and half duplex, and there are no nfs problems. 

Cisco said they had some internal docs talking about problems with the
Intel 100B cards running 100 megabit, full duplex, that were cleared up
with the 100+ cards.  Intel was completely useless.  

I'm wondering if there is perhaps a problem with the fxp driver in 2.2.6,
or some weird issue with the Cisco.  I don't have another 100 megabit
switch laying around, and I really wouldn't want to have to switch from
the Intel cards not knowing what the problem is.  All that Cisco could
suggest was different cards or a sniffer to look for more clues.

Any ideas?  This seems pretty weird.

Thanks.
