Update: I'm not using the standard Nvidia driver because I of a bug in the r8169 driver (see bug 821454). To fix that, I installed kernel 3.0.1 (see comment #3).
After that, I needed the Nvidia driver from xorg edgers (nvidia-current_285.03-0ubuntu1~edgers~natty1_amd64.deb)
A workaround to fix the bug here, I removed nvidia-current, did the update and reinstalled.
