Erratum
The Aero Acceptance Test is exposed for Windows 7 Ultra
Mobile System Submissions. However, the requirement this test
enforces is only required for Desktop, Mobile and All-In-One
Windows 7 PC's. This errata covers ANY failures in the
AeroAt.exe's test log, as long as the test completes. Note the
test should still run to completion and create a log file, this
errata would not cover hangs or crashes in the user mode
display driver.

Erratum
The European Union requires the headphone output level to be
<= 150 mVrms for headphone jacks. There's a note in WLP
requirement AUDIO-0006 that states, in the presence of
regional regulations, the output level requirement for
headphones is dropped from >= 1000 mVrms to >= 120 mVrms.
This provides freedom for manufacturers to meet both the EU
<= 150 mVrms @ 32 Ohms and the WLP >= 120 mVrms @ 32
Ohms requirements. The Fidelity Test tests headphones at 300
Ohm load, though. Without knowledge of the output impedance
at the jack, the test cannot extrapolate what the output level at
32 Ohms would have been from the output level at 300 Ohms.
The test assumes that the output level at 32 Ohms will be
*less* than the output level at 300 Ohms, though. So any
measurement >= 120 mVrms at 300 Ohms "could be" a passing
result, depending on the output impedance.

Erratum
Fidelity uses too small of a buffer and wakes up too
infrequently during the System Activity test. This causes errors
like: Noise level during system activity on (left or right) channel
73.2016 dB: *** FAIL *** (requirement >= 80 dB)

failures but are not a requirement till January 2009. A filter is
being created for the above assertions for this particular device.

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.
