Tommy_CZ, the next step is to fully reverse commit bisect from kernel 4.4 to 4.7 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. 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. Also, the kernel release names are irrelevant for the purposes of bisecting. After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed. Thank you for your help. ** Tags added: kernel-fixed-upstream-4.7 needs-reverse-bisect regression-update ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1606384 Title: Ubuntu does not boot with systemd Status in linux package in Ubuntu: Incomplete Bug description: Ubuntu does not boot with systemd, it boots with upstart choice in grub.
