Erratum
The HD Audio class driver hdaudio.sys exposes AC-3 data ranges on
S/PDIF Kernel Streaming pins incorrectly.
The compressed AC-3 transport is "stereo", "16-bit", and at the same
sample rate as the uncompressed format. As such, AC-3 data ranges
are expected to have MaximumChannels = 2, and MinimumBitDepth
= MaximumBitDepth = 16.
However, the HD Audio class driver sometimes incorrectly exposes a
MaximumBitDepth of 24 or even 32.

Compliance Test For

401
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

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
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.

Error: attempted to set unsupported EPT 0b10 (Reserved); previous
value was 0b01 (Reserved); response was 0b10 (Reserved) For
unsupported EPTs, the pin must either retain the previous value or

Erratum
The HAL Timer test can fail the KeStallExecutionProcessor Backoff
Test case due to an issue with the processor implementation. This
has been determined to be a problem with the test.
