[eepro100] eepro100 crashing with D815EEA motherboard

[Brian Hirt]

I just wanted to follow up on my message with some information
I learned that may help the developers.

Like i stated below, all of my D815EEA/RH6.2 systems crash 
whenever the 1.11a eepro100 driver is initialized at 100Mbps, 
so I initialize at 10Mbps (however that has other problems).  
Actually the "modprobe" doesn't crash the machine, but the 
"ifup" does, 100% of the time.  I found that if I run 
"mii-diag eth0 -A 100baseTx" on the interface after it's up
and running, it seems to work -- at least I haven't been able
to get it to crash yet.

I'm going to have access to these machines for a few more
days before they go to the datacenter.  During that time,
if there is anything I can do (which doesn't include kernel 
debugging/programming; unless I'm being hand held) to help 
locate the problem in the eepro100 driver, please let me know.  

Thanks,

Brian
