nocrs [X86] Ignore PCI host bridge windows from ACPI.
If you need to use this, please report a bug.
+ use_e820 [X86] Use E820 reservations to exclude parts of
+ PCI host bridge windows. This is a workaround

routeirq Do IRQ routing for all PCI devices.
This is normally done in pci_enable_device(),
so this option is a temporary workaround
