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
Assertion 5FC5B29C-0F24-423B-856A-87C9E31C6802 Bit 14
(Completion Timeout Mask) in the Uncorrectable Error Mask
register (offset 8h) in the Advanced Error Reporting Capability
table must be read-writable . Assertion 908C881D-29ED-4B57-
A1A6-BE1DBD45522E Bit 14 (Completion Timeout Error
Severity) in the Uncorrectable Error Severity register (offset Ch)
in the Advanced Error Reporting Capability table must be read-
writable . These failures are incorrect for PCI Express switch
ports that do not issue Non-Posted Requests on their own
behalf (vs. only forwarding such Requests generated by other
devices).

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.
