Thorsten, That means something went wrong in the bisection process. Probably the issue does not happen all the time? Here's my suggestion: - Instead of warm boot (reboot), always do a cold boot (shutdown then boot). - Test with more S3 cycles before next bisect. -- You received this bug

[Kernel-packages] [Bug 1722478] Re: Two-finger scrolling no longer works after resuming from suspend

First, make sure 4.11 is working. I can build kernel for you, but it will take a dozen iterations. It can be much faster if you build your own kernel locally, $ sudo apt install git $ sudo apt build-dep linux $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git $ cd linux
