Indeed, the log you posted looks like a driver problem: Jan 31 13:39:05 leon-desktop kernel: [ 46.901348] rtl8187: Card successfully reset Jan 31 13:39:10 leon-desktop kernel: [ 51.597988] BUG: unable to handle kernel NULL pointer dereference at virtual address 00000000
If blacklisting it solves the error, it will also allow you to keep the network-manager installed. AFAIR this is necessary to keep ubuntu-desktop installed, which makes administration/upgrades much easier :) Anyway, I will test both here on friday (removing the network-manager then blacklisting and reinstalling it). -- (Feisty) NetworkManager makes system unusable, seems to have problem with dbus https://launchpad.net/bugs/83013 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
