Installation

Installing Arch was mostly without hiccup, you do need to disable Secure Boot (F10 for UEFI options; F9 for boot options). Dual boot was not tested. The laptop does not have a CD drive, so you have to use a USB stick. The UEFI also would not startup from the USB stick, but you can browse the USB, and choose the loader.efi to startup from.

Audio

Only the front speakers work out of the box.

Accelerometer

The accelerometer is not found by any userspace programs, iio-sensor-proxy gives the following output: 

G_MESSAGES_DEBUG=all /usr/sbin/iio-sensor-proxy
** (process:12472): DEBUG: 11:45:31.305: Could not find any supported sensors

The accelerometer is connected to a new Intel Integrated Sensor Hub which is not supported by the kernel yet, but can be manually bound to the intel-ish-ipc driver: 

$ lspci -nn | grep 8086:a135
00:13.0 Non-VGA unclassified device [0000]: Intel Corporation Sunrise Point-H Integrated Sensor Hub [8086:a135] (rev 31)
# modprobe intel-ish-ipc
# echo "8086 a135" > /sys/bus/pci/drivers/intel_ish_ipc/new_id
