This task depends upon
Thus I used:
git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-stable
git bisect bad v3.14.3
git bisect good v3.14.2
My result:
Before last step:
[root@dixi-arch linux-stable]# git bisect bad
Bisecting: 0 revisions left to test after this (roughly 0 steps)
[e7573909b5b8df35591a66146d8629f7aa41675e] xhci: Prevent runtime pm from autosuspending during initialization
After last step:
[root@dixi-arch linux-stable]# git bisect good

xhci: Switch Intel Lynx Point ports to EHCI on shutdown.
commit c09ec25d3684cad74d851c0f028a495999591279 upstream.
The same issue like with Panther Point chipsets. If the USB ports are
switched to xHCI on shutdown, the xHCI host will send a spurious interrupt,
which will wake the system. Some BIOS have work around for this, but not all.
One example is Compulab's mini-desktop, the Intense-PC2.
The bug can be avoided if the USB ports are switched back to EHCI on
shutdown.
This patch should be backported to stable kernels as old as 3.12,
that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016

I build a customized Kernel with Arch Stock as basis; with only ONE change:
I deleted in Line 138, not in Line 121 in drivers/usb/host/xhci-pci.c
xhci->quirks |= XHCI_SPURIOUS_REBOOT;
and issue disappears -> everything works fine now
