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. Signed-off-by: Feng Tang <feng.tang@intel.com> --- arch/x86/pci/acpi.c | 10 ++++++++++ 1 file changed, 10 insertions(+)
