For the S1,S2 failures, The failures come from firmware not provide _S1 and _S2 objects, so that the kernel complains about cannot find _S1,_S2 namespace objects that contains the register values for the sleep state when kernel would like to setup all the sleep state information. This means kernel don't know how to enter S1/S2 sleep state. But it should not be a problem if the S1/S2 sleep state isn't supported intentionally.
A patch had been sent to lower the failure level on fwts of the _S1 and _S2 objects cannot be find. Please refer to and follow by the bug#1279714. It should be worked after fwts version V14.02.00 ** Changed in: linux-lts-trusty (Ubuntu) Status: Incomplete => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1285477 Title: [Dell Latitude 3440] fwts HIGH failures To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1285477/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
