Title:
  False positive ACPI _PRS error messages

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  New platforms have hardware registers for routing table implemented as
  "write once". Once set by UEFI firmware during POST, OS will not be
  able to modify the routing table, and ACPI _PRS method are removed
  according to ACPI spec.

  As a result, generating the error messages "ACPI Exception:
  AE_NOT_FOUND, Evaluating _PRS" in kernel by default does not make
  sense, and they should be muted by default.
