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: <---//first log with old driver//--- May 22 16:52:40 mega2 kernel: e1000e: Intel(R) PRO/1000 Network Driver - 1.4.4-k May 22 16:52:40 mega2 kernel: e1000e: Copyright(c) 1999 - 2011 Intel Corporation.
