Problem with igb and quad card

idata · ‎08-14-2012

Hello

Form several days we have a problem with quad cards on debian squeeze and module igb.

This cards are connected to two diffirent networks but we have random error, dropped and frame packets on random interfaces.

Has anyone had similar problem ?
