partially working touchpad 4.14.0-041400rc7
This is the dmesg of my ubuntu 16.04 installation with the
4.14.0-041400rc7 kernel. It has the trackpad working but not its
left/right buttons.
After this kernel mainline release, the touchpad is not working at all.

Ubuntu 16.04, Jumper ezbook 3 pro V4: patch is not working.
Compiled by myself with this patch 4.14.0-041400 and tried a kernel
compiled by a more pro user than me (here.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1728244).
Touchpad is not working. The only semi working kernel is the
4.14.0-041400rc7 on mainline. Yes MOVING, Yes doubletap for clic, No
buttons.

@mogio, I just noticed this in your dmesg log.
"random: fast init done"
If it means you have "fast boot" enabled in your BIOS you should disable that.

@mogio a guy on the TT forum says that 4.15 did not work for him but rolling back to 4.14.3 did. I'm not sure but I think he's using Ubuntu. 4.14.3 has also been working for me without failure (so far). Manjaro just released 4.14.5 so I will be upgrading and testing that out soon.

Same problem here on Chuwi LapBook Air
touchpad showing as ALPS0001:00 0911:5288 Touchpad
tried kernels 4.14.14 through 4.15.1 including discussed patches and all no goor on Arch Linux.
I have magaed to bodge the touchpad to work by constantly removing and
re-adding the driver using modprobe but on first suspend, if the
touchpad is enabled, my system crashes.
Any news would be helpful.

4.14, 4.15, 4.16... still not working.
>From ubuntu mainline...
the last semi working touchpad (movements are ok, physical buttons are
not working) is the drm-intel-next 4.14.0-997.201712022100. After this:
kaput. :)

Title:
Touchpad stops working after reboot on Apollo Lake
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Triaged
Bug description:
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.
This is mesg | grep i2c_hid:
[ 2056.460636] i2c_hid i2c-SYNA3602:00: i2c_hid_get_input: incomplete report (27/34)

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