I'm pretty confident this will fix pci=use_crs on *some* machines even if Pete's problem turns out to be something else, so I think we should just put it in. --- Bjorn Helgaas (1): x86/PCI: ignore Consumer/Producer bit and parse additional _CRS resources arch/x86/pci/acpi.c | 77 +++++++++++++++++++++++++++++++++++++++++++++++---- 1 files changed, 71 insertions(+), 6 deletions(-)
