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.est assertion
failure is allowed DDC2C294-795E-4587-AF61-
33F70362C2AF.

Erratum
Certain HD Audio codecs allow setting unsupported
VRef settings in the pin control register. They have
hardware validation that prevents the unsupported
VRef settings from affecting the actual voltage, but
subsequent reads from the pin control register will
return values that are out of sync with what the
actual voltage is. This requires a hardware fix so the
failure is forgiven for these specific codecs. Future
designs must advertise the VRefs correctly. The
failing test log is UAATest.wtl.

TCG TPM

Test

Erratum
The Trusted Computing Group (TCG) specifies
guidelines for Platform Configuration Register (PCR)
operation within a Trusted Platform Module (TPM).
This test, TPMSysInt.exe, has identified an error
while attempting to extend a value into PCRs 17 -
22. Windows is expecting the return code
TPM_BAD_LOCALITY (TPM_BASE + 61) as defined by
the TCG. Windows Vista is currently not using these
PCRs. Although Windows Vista is not currently using
these PCRs, these PCRs will be in use in the future
versions of the operating system. Microsoft highly
recommends that this issue be corrected by
contacting the TPM or platform manufacturer instead
of applying this filter
