If you build with CONFIG_PNPACPI=y and boot without "pnpacpi=off",
PnPACPI will fail with the warnings below --
fixed by the additional patch below.
thanks,

In ACPICA 20051117, acpi_walk_resources() started
sending ACPI_RESOURCE_TYPE_END_TAG to the callback
routine which wasn't prepared for it, causing
_CRS to fail and PnPACPI to not recognize any devices:
pnp: ACPI device : hid PNP0C02
pnp: PnPACPI: unknown resource type 7
pnp: PnPACPI: METHOD_NAME__CRS failure for PNP0c02
