Hi Bart,

In your previous comment you set that linux-
image-4.14.0-997-generic_4.14.0-997.201712022100_amd64.deb is working,
now you say that 4.14.0-041400rc7 is the latest working, and that 4.14
final does not work?  linux-
image-4.14.0-997-generic_4.14.0-997.201712022100_amd64.deb sounds like
it is a final (non rc) build?

Note I'm not an Ubuntu developer, so I don't know how Ubuntu's kernel
versioning scheme works.

If the generic kernel builds broke between 4.14-rc7 and 4.14.0 final
then it should be easy (I hope) to pinpoint the problem. Also note that
some people say rebooting is an issue so you should probably do a
poweroff and then a cold boot for each test.

Also it is interesting to see if things don't work if doing a manual
rmmod i2c-hid; modprobe i2c-hid helps.

  Touchpad stops working after reboot on Apollo Lake

Status in Linux:
Status in linux package in Ubuntu:

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

  uname -rvps

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