I don't think you have the same issue, the problem in bug 1526312 is a touchpad with missing descriptors. I think what you are seeing is the same i2c-hid touchpad power-management issue as other people or seeing on various ezbook models. This is currently being discussed here: https://bugzilla.kernel.org/show_bug.cgi?id=199821 The touchpad should work after a suspend/resume. You may need to do: sudo rmmod i2c-hid sudo modprobe i2c-hid After suspend-resume.

I believe that this is fixed by: https://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid.git/commit?id=807588ac92018bde88a1958f546438e840eb0158 Which is queued for merging into 4.19: https://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid.git/log/?h=for-4.19/fixes The patch has a Cc stable, so this will hopefully show up in stable kernels soonish. Since this affects quite a few laptop models it might be a good idea to add this as a downstream patch to the Fedora kernels for now.
