[Bug 1330844] Re: I installed ubuntu14.04LTS in LenovoG510(4th gen intel i5 processor, 4G, 500HD, 2.5GH, ). Very often(every 30 minutes) wired connection lost and will be restored only when system is rebooted. And also durind file sharing from server, downloads from dc++ system freezes completely and have to hard power off. Here are the outputs of few commands run when connection lost.
