Check your /etc/sysconfig to see which interface is trying to be ifconfig'ed?
It should be "ed0" judging from your message above.

Looks like the kernel isn't getting the IRQ.

(a) Check if the card IRQ matches with what the kernel thinks the IRQ is?
    If I remember right, the probe just looks for the card at the configured
    IRQ address by reading and writing device memory.  Send or recieving a 
    packet uses the interrupt which isn't checked at probe time.  
    
    If necessary, run your DOS tools to see the IRQ the card is actually
    configured for.  What is printed at startup time is the kernels idea of
    the IRQ, not the cards actual configuration.

    Note that this is different from there being any `conflict' of IRQ's 
    assigned.  

(b) I've seen problems with older NE2K cards on the newer P5 motherboards.
    Does your card work in the same machine from under DOS?  Sometimes 
    fiddling with the motherboard settings (io wait states) etc may help.
