Erratum
Run AC3 test on a system with the Microsoft HD Audio class
driver installed. Expected results: All AC3 kernel streaming data
ranges should advertise MinimumBitsPerSample = 16 and
MaximumBitsPerSample = 16. Actual results: HD Audio class
driver sometimes advertises MaximumBitsPerSample = 24.

513
Erratum
UAA Test requires the Traffic Priority bit to be read/write -
however there are two specs that apply, and they conflict. One
says the bit must be read/write, the other says it must be read-
only. Contact has been made with the author of both specs
(Intel) but until this point is clarified we cannot fail submissions
containing this test failure.

Erratum
PCI Compliance: Bit range 23:0 (Organizationally Unique
Identifier)in the Serial Number 1st DW register (offset 4h) in the
Device Serial Number Capability table cannot have a value of 0h
as it must contain a value assigned by IEEE.

Erratum
This happens because the PCI Compliance test assumes that if
the Data Link Layer Link Active Reporting Capable bit in the Link
Capabilities register for a given PCIe port is set then that
indicates that the Data Link Layer Link Active bit will also be set.
This is an incorrect assumption because the Data Link Link
Layer Link Active bit can be reset when there is no device
below the port. This assertion needs to be removed from the
PCIHCT. The current architecture of the PCIHCT prevents it from
knowing whether devices exist below a bridge/port.

Erratum
The following PCI Compliance test failure is acceptable: Bit 15
(Bridge Configuration Retry Enable) in the Device Control
register (offset 8h) in the PCI Express Capability table must be
read-only and always return 0 as it is reserved for devices other
than PCI Express to PCI/PCI-X Bridges. Assertion 13A41D3E-
2576-41DC-A67C-525DA3637CEA This failure is acceptable
because this is a PCIe 1.1 feature and the WLP requires
compliance with only PCIe 1.0a.
