Created attachment 854513 [details] dmesg of last 10 boot This is result of - sudo journalctl -o short-precise -k -b -10 > dmesg10boot.log This includes boots that did not have the problem, then when the problem occurred and of the latest boot when rolledback to previous kernel and things are now working fine. the very first image (https://bugzilla.opensuse.org/attachment.cgi?id=854509&action=edit) are from the last boot prior to the rollback to old kernel. Pls instruct me whatever more is needed (with command)as am not well versed with linux commands.
