Intel I350-T4 only recognized by Esx 5.5, not by 5.5 U2

Hi all,

I relative new to ESx, sind 5.0.

Until 5.5 all went fine, inserting the Quadport I350 in 5.5, rebooting, NICs were recognied. Made an Udate to 5.5 U2 via ESX-Cli and the four ports disappeared.

MAde the update via CD again (maybe somethng went wrong) , message, no adaper recognized. With intel igb 5.2.7 driver in Image

MAde a clean 5.5 U2 install, same message.with intel igb 5.2.5 in Image

MAde a new 5.5 Install with base image, Adapter are back with vmware-igb 2.*.

Update of the driver to 5.2.5 with cli went fine- Reboot, Host not pingable.

Does anyone have an idea?

It´s a play system no need to hurry up.

regards,

Christian
