Alejandro Virrueta, the mainline kernel is not supported as per https://wiki.ubuntu.com/Kernel/MainlineBuilds#Does_the_kernel_team_support_the_mainline_kernel_builds.3F .
Despite this, if it continues to work without problems, if you would like a backport to Trusty, the next step would be to fully reverse commit bisect the kernel in order to identify the fix commit following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F . Just finding adjacent kernel versions is not fully commit commit bisecting. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1326097 Title: [Lenovo ThinkPad W530] Does not stay suspended To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1326097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
