al, please see https://wiki.ubuntu.com/Kernel/MainlineBuilds#Does_the_kernel_team_support_the_mainline_kernel_builds.3F .
Despite this, the next step is to fully reverse commit bisect from kernel 3.19 to 4.0.4 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ? Please note, finding adjacent kernel versions is not fully commit bisecting. Thank you for your understanding.
