I'm trying out the patch vs 4.4.0-16 (on Xenial) and 4.4.0-14 (on Trusty) on a couple of T460s machines using apt-get source linux-image-4.4.0-16-generic && cd linux-4.4.0 && patch -p1 < ../../t460-smm-pstates.patch && dpkg-buildpackage I'm not sure this is the right approach, but the advice at https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel didn't work for me (is it out of date?) I built and installed with the patch OK (i.e. no hang on lid close) on Trusty using make deb-pkg CONFIG_LOCALVERSION=-blah but K/BYOK advises against it. ** Bug watch added: Linux Kernel Bug Tracker #110941 http://bugzilla.kernel.org/show_bug.cgi?id=110941 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561974 Title: [Lenovo T460s] freeze on battery + lid close To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1561974/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
