Subject: Sun3 Ethernet card causing crash during ifconfig?
Date: 31 Aug 92 01:04:16 GMT
Organization: Center for Computer Music Research and Composition, UCSB

I have installed a third Sun ethernet card in our Sun 3/160.  

In testing this new ethernet card, I first installed it in place of the ie1 card
(with the addresses appropriately set) and it worked just fine.  This leads me
to think that it may just be some kind of hardware configuration mistake on my
part in its new functioning as ie2.

When all three cards are in place, the new kernel has no trouble finding the 
third card, and the machine boots up correctly, i.e., the original two activated
interfaces (ie0 and ie1) work normally.  Here is a portion of the boot sequence
printout:

I purposely left the ifconfig call to the new interface out of the rc.boot
script so that I could call it by hand.  When I did it as follows, the machine
crashed.  I include the entire crash message below.  My question is, what does
this crash represent?  Is it a hardware problem?  What is the best way to
proceed from this point?

Thank you in advance.
