From 3f7a7934c2136ec916d98c556e3682c100fb1849 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Wed, 10 Oct 2012 16:27:47 +0800 Subject: [PATCH] x86/PCI: Add quirk for "CheckPoint P-20-00" to not use bridge _CRS_ info This is to fix a regression https://bugzilla.kernel.org/show_bug.cgi?id=47981 The CheckPoint P-20-00 works ok before new machines (2008 and later) are forced to use the bridge _CRS info by default in 2.6.34. Add this quirk to restore its old way of working: not using bridge _CRS info.
