So several people here are reporting that touch is not working for them
at all, starting with 4.15 kernels, where as 4.14 works but does not
have working buttons. The buttons thing is known and fixed (I believe),
but that is of little help if touch no longer works at all.
I've a feeling that this might be related to my commit to fix touch on some
I'm attaching a revert of that patch, if someone (Bart?) can build a
4.15 generic kernel with that patch to revert the commit added and test
that, then that would be great.
If reverting that commit does not work then someone will need to do a
bisect between 4.14 and 4.15 to figure out what in 4.15 breaks the
** Patch added: "Patch to revert a commit which may cause the problems people
are seeing with 4.15"

Touchpad stops working after reboot on Apollo Lake
Status in Linux:
Status in linux package in Ubuntu:
On the Jumper EZBook 3 Pro (V4) laptop, using an Apollo Lake N3450
processor, if you install Ubuntu 17.10 (or less) with isorespin and
use rEFInd as bootloader (this is the only way to get linux booting on
this laptop) everything works out of the box, but after a reboot or
two the touchpad stops working. Both in Ubuntu and Windows 10. The
only way to restore functionality is to boot from usb key ubuntu 17.10
respined, or disassemble laptop and detach-reattach battery cable.

There has to be a bug in the kernel. Any way to avoid this?
