I have updated my bios according to previous message. Bug remains identical and same problem occurs with the new kernel 3.19.0-18. This seems to be a compatibility issue with my ethernet adaptor as WIFI seems to work correctly.
I will issue an apport-collect command following this update ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Description changed: this is a follow -up logs from 1) uname -a > uname-a.log 2) cat /proc/version_signature > version.log 3) dmesg > dmesg.log 4) sudo lspci -vnvn > lspci-vnvn.log are in attachment --- ApportVersion: 2.17.2-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: eric 2349 F.... pulseaudio /dev/snd/controlC0: eric 2349 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 15.04 HibernationDevice: RESUME=UUID=8b4bc51b-4c9c-4e1e-823d-7daca442aab6 InstallationDate: Installed on 2014-06-08 (344 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" -
