Hi folks,

commit in $Subject breaks rebooting an HP laptop here with a Carrizo
chipset: after typing "reboot" and pressing Enter, it powers off the
machine up to a certain point but the fans remain on, screen goes black
and nothing happens anymore. No reboot. I have to power it off by
holding the power key down for 4 seconds.

Reverting the patch fixes the issue.

GPU info on that machine:
