network stalls on Fedora Core 3

[Keith Fetterman]

David,

I am fairly sure that I have ruled out this problem .  I have tried 
different cables, different sockets in the wall and different ports in 
the switch.  I have tried different ethernet cards.

The cables were factory made.

I have a working Red Hat Enterprise 3 Linux system sitting next to it. 
I've plugged that ethernet cable into the FC3 system.  The FC3 system 
still fails.

I replaced the FC3 OS with RHE3.  When RHE3 was running on the same 
hardware, I didn't experience the problem.

Is it possible the drivers included with FC3 are more sensitive to 
hardware issues, than RHE3 linux?

Thanks,
Keith
