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:

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