I have really great troubles with the onboard-nic (Realtek RTL8111/R8168) and my Ubuntu-Server 12.04: Every 3 hours the server is going to become unresponsible. Then the server breaks down completely.

The syslog says about the nic (05:00.0):

I have tried to install the official driver of this realtek-nic, but with no success. But when I install Debian 6, all the problems are gone and the server works fine. When I reinstall Ubuntu-Server-12.04 I have the same problem.

Any suggestions what I can do?

Thank you and greetings, Nico H.

The AMD-Vi may mean a virtualization issue. Please go into BIOS setup and then try to disable any virtualization or AMD-V settings. Please report back if this helps so I can add an answer for future users. –  hexafraction Jul 23 '12 at 11:25
    
Ok sounds interessting, but what is the connection between the AMD-Vi and the nic. lspci says, that the device with the ID 05:00.0 is a realtek rtl8111/8168 nic. When I disable the AMD-Vi, I can´t virtualize via KVM, can´t I? greetings –  Nicolas Nox Jul 26 '12 at 13:33
    
It's trying to communicate with the NIC through AMD-Vi, and I suggest you try disabling it. –  hexafraction Jul 26 '12 at 14:04
    
Ok, it so could it be a BIOS-bug or could it be a driver problem? greetings –  Nicolas Nox Aug 3 '12 at 21:14
    
Essentially, it could be. –  hexafraction Aug 3 '12 at 22:29
