*bump* :-) Second the previous comment about traffic being relevant; I recently clean-installed 8.10 (with network-manager) on an old box. Sure enough, as soon as I started transferring larger amounts of data across the network (be it streaming or copying large files), network-manager thinks the network card (eth0, in my case) link goes down repeatedly.
When copying a large file (it's on a 100 Mbps switch) this happens every 1 to 30 seconds. When streaming video on the other hand, it happens every 2 to 15 MINUTES. So it definitely seems related to the amount of traffic going through the network card. Uninstalling network-manager and configuring /etc/network/interfaces myself fixed it. I haven't had a single "eth0: link down" in my log since uninstalling network-manager. For reference, here's my current (working)/etc/network/interfaces (though the ppp0 is obviously not relevant here): # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp iface ppp0 inet ppp provider ppp0 auto ppp0 -- New networkmanager null assert in Hardy https://bugs.launchpad.net/bugs/227819 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
