I found package which is the source of the problem! Problem appears after upgrading network-manager package 0.9.4.0-0ubuntu4.2 to 0.9.4.0-0ubuntu4.3
So it seems to be not kernel bug, but it is a bug of the network- manager! Next step is to find out which changes were made to the network-manager package! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1268556 Title: 8086:1502 [Fujitsu D3076-S1x] Ethernet disconnecting at boot and later To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1268556/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
