[PATCH 4.4 06/67] x86/reboot/quirks: Add iMac10,1 to pci_reboot_dmi_table[]

From: Greg Kroah-Hartman
Date: Wed Jan 27 2016 - 15:35:45 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mario Kleiner <mario.kleiner.de@xxxxxxxxx>

commit 2f0c0b2d96b1205efb14347009748d786c2d9ba5 upstream.

Without the reboot=pci method, the iMac 10,1 simply
hangs after printing "Restarting system" at the point
when it should reboot. This fixes it.
