Hi,

one of our rented root-server has a problem with the network-adapter.The network is interrupted from time to time and i can not longer connect to our server. We can only reboote (remote) the server and restart the network. I think it was an network-driver-problem from an "Intel Corporation 82574L Gigabit Network" --- e1000e But now i have install a new kernel-driver and i have the same problem again.

Here an extract of the logs:
