Subject: [PATCH] PCI: Add new PCI id for Intel GPU interrupt quirk
Date: Mon, 07 Apr 2014 15:10:32 +0200	[thread overview]
Message-ID: <3185796.STv3LRO1j8@storm> (raw)

After a CPU upgrade while keeping the same mainboard,
we faced "spurious interrupt" problems again.

It turned out that the new CPU also featured a
new GPU with a different PCI id.

-> Add this PCI id to the quirk table. Probably all other
Intel GPU PCI ids are affected, too, but I don't want
to add them without a test system.
