보드는 S5000V SA입니다.
이더넷카드는 Intel Co. 80003ES2LAN Gigabit Ethernet Controller 이라고 표시가 되어있어요.(Centos 네트워크 설정 상에서)
eth0, eth1 인데
dmesg |grep e1000
e1000e:Intel(R) PRO/1000 Network Driver - 0.3.3.3-k4
e1000e:Copyright (c) 1999-2008 Intel Corporation.
e1000e: probe of 0000:05:00.0 failed with error -2
e1000e: probe of 0000:05:00.1 failed with error -2
이렇게 나오네요..이렇게 나오면 정상적으로 인식한거 같지 않은데
어떻게 해야하나요?

몇일동안 삽질했다는 내용중 "2009/4/28 3:57" 에 달린 댓글에 내용이 있네요. 밑에서 두번째.
BIOS setting (Advanced/PCI) called IO Acceleration Technology 부분을 조정했다고 하네요.
테스트 한번 해보시죠.

Sorry for the lengthy delay in posting. I spent several days playing with this problem and I found the solution! There is a BIOS setting (Advanced/PCI) called IO Acceleration Technology. Once I disabled that setting, then all was fine. Being my stubborn self, I was not satisfied with just having it working, I wanted to know what that setting did. I poked around a bit with the setting both enabled and disabled. What I found was that with the setting enabled, It enables both TX & RX checksumming. With the setting disabled, it only enables TX checksumming (as listed by ethtool -k).
Also I was incorrect in my previous post that 5.2 used e1000 driver. I did another load of 5.2 and it was using an older version of e1000e, but that older version did not support the RX checksumming on chip, so it never crashed, however the newer e1000e driver does support it when enabled, but is apparently broken. Turning off RX-Checksumming with the ethtool tool did not have any effect. Only disabling in BIOS made a difference.
So... after boring everyone with my lame diagnosis.... the simple fix (at least for me) was to disable the "IO Acceleration Technology" option in BIOS.
Thanks to Alan for the assistance and giving me some things to look at!!!

바이오스의 설정부분을 봐보시는게 좋을듯합니다. 함 참고해보세요.
