Can you please do that? The steps will involve compiling and testing a couple of kernels, but given we will use a targeted config, things should go reasonably fast, and you have a clear idicator when things are 'bad'. As I understand every 7.1.y release was a problem, so looks we should bisect between v7.0 and v7.1 (but if that understanding was wrong, then we should adapt the following procedure): git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git cd linux git checkout v7.0 cp /boot/config-$(uname -r) .config yes '' | make localmodconfig make savedefconfig mv defconfig arch/x86/configs/my_defconfig # test 7.0 to ensure this is "good" make my_defconfig make -j $(nproc) bindeb-pkg ... install the resulting .deb package and confirm problem does not exist # test 7.1 to ensure this is "bad" git checkout v7.1 make my_defconfig make -j $(nproc) bindeb-pkg ... install the resulting .deb package and confirm problem exists With that confirmed, the bisection can start: git bisect start --first-parent git bisect good v7.0 git bisect bad v7.1 (note the --first-parent flag for the bisect start, this is useful as we bisect in mainline where we will see a lot of merges from other branches) In each bisection step git checks out a state between the oldest known-bad and the newest known-good commit. In each step test using: make my_defconfig make -j $(nproc) bindeb-pkg ... install, verify if problem exists and if the problem is hit run: git bisect bad and if the problem doesn't trigger run: git bisect good . Please pay attention to always select the just built kernel for booting, it won't always be the default kernel picked up by grub. Iterate until git announces to have identified the first bad commit. Then provide the output of git bisect log In the course of the bisection you might have to uninstall previous kernels again to not exhaust the disk space in /boot. Also in the end uninstall all self-built kernels again. Regards, Salvatore
