I tried to connect O2 to Origin2000 rackmount with module A and B, and
I got message as:

"ALERT: ef0: rx SSRAM hardware parity error
ALERT: ef0: tx SSRAM hardware parity error"

I have made sure the ethernet card on O2 is working fine since I could
visit internet. I guess the ethernets in either model A or B are both
out of order. Could someone explain what happened in the ethernet card
in Origin2000.
