Please confirm: with both a Tulip and a 3Com card you observed the problem ?
What is at the other end of the cable ? A Cisco switch by any chance ?
When the problem appears, could you please run "arp -n" and see if you get 
any "incomplete" entries ?

This seems like a different problem: incorrect media settings. If you send 
the large amount of data, what hangs: the transfer itself or network 
communication in general (a ping at the same time) ? Only transfer hanging 
would most likely be a media mismatch, in this case you should also see 
some error messages in the logs. If it's the network hanging, would it be 
possible to run the diag tools (mii-diag and vortex-diag) while the 
network is in this state ?
