Touchscreen not working properly after Kernel update 4.3rc3-rc3 -> 4.3.3-33/4.3.3-36/4.4.0-55

Just got known of your arch repo and thougth to try out your newer kernel version.
Before I had already your kernel but in version "4.3rc3-rc3". About everything worked there which is necessary for basic usage of device.
With upgrading thorugh your repo to any of your newest kernels you have threre, my touchscreen does not work anymore :( - any idea here what could have gone wrong. As I don't have old kernel files anymore i can't downgrade.

Besides: Like you mentioned in #1 there is no wifi at 4.4.0-55 at my system, too.

What device do you have? On my T100TAF touch/multitouch works like a charm.
Could you post your dmesg?

current stable kernel is: linux-T100-4.3.3-33
linux-T100-bfs and -dev can be unbstable

Update: Sorry for long delay, see attached file dmesg.txt

I've got the T100TA 32Gb with optional HDD in Dock. Currently that laptop is in use for printing, i will post dmesg later.

I did some further tests, interestingly besides shutdown/buttons/suspend stock arch kernel is best at my machine:

Linux localhost 4.3.3-2-ARCH: +sound +touchscreen +wlan -suspend
Linux localhost 4.4.0-rc7-0: -touchscreen* +suspend
Linux localhost 4.3.3-38-T100-bfs: -touchscreen* +suspend

Is that your expected behavior? From my understanding if you would base on stock arch kernel add your patches for suspend/buttons and we'd have a pretty good kernel. :)

*With "-touchscreen" i mean that it looks like it is sensitive everywhere, but verticaly only some small area at upper part of screen is used for curser.

Just another update with attached dmesg:

Linux T100 4.4.0-rc8-0 -touchscreen -suspend(?) -sound +wlan

I don't know why suspend is not working anymore, but could be something with my very own device so don't mind it i guess. Still stock arch kernel works best.

Experiencing the same with http://bazdara.com/arch/i686/linux-T100-4.3.3-33-i686.pkg.tar.xz
