I'm facing the same problem after upgrading from oneiric to precise. The following workaround works for me till this is fixed upstream:
There is a debian package in sid which provides the latest Realtek driver (8.029.00) including dkms configuration
http://packages.debian.org/de/sid/all/r8168-dkms
The nice thing about this is that it automatically re-compiles the r8168 module on kernel updates.
