Denis, what do you mean by works for Lynx Point? Do you mean that
adding the quirk to switch the ports on EHCI on shutdown (e95829f474)

Denis, do all of Compulab's Haswell systems reboot on shutdown? Are
they all running a Phoenix BIOS? Can you send me the output of `sudo

Some devices with Intel Panther Point chipset may require switchover
usb ports from XHCI back to EHCI controller before shutdown.
Overwise various BIOS bugs related to power management may be
