I can not use "ubuntu-bug linux" because it has no options and wants to report only for the currently running kernel, which has no network connection. For some reason I can only attach one file. I chose to attach the kern.log - the version.log shows only the currently running kernel, and I can paste the lspci log later if required. > lsb_release -rd Description: Ubuntu 14.04.3 LTS Release: 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-utopic/+bug/1488024/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
