dmesg output, DSDT

Tried to run Arch Linux on Linx 7 (http://www.linx-tablets.com/linx-7.html),
works/boots on 3.14.37-1-lts kernel.

When I upgrade to kernel 3.15> <=3.19, I can only boot with acpi=off as kernel
parameter.

Unfortunately it hangs/freezes at initial ramdisk (on upgraded kernel), and I'm
unable to provide any (display) output.
So I have provided output/debug info from the 3.14 kernel.

Many Thanks!

PS. Reason for upgrade: touchscreen support (Goodix), drivers, fixes for btrfs,
etc.
