BJ81.
Execution of BIST During Cold RESET Will Result in a Machine Check
Shutdown
Problem:
If BIST (Built In Self-Test) is enabled and a Cold RESET follows, an unrecoverable
machine check shutdown will occur.
Implication:
Due to this erratum, BIST cannot be enabled.
Workaround:
None identified.
Status:
For the steppings affected, see the Summary Tables of Changes.
BJ82.
PCI Express* Differential Peak-Peak Tx Voltage Swing May Violate the
Specification
Problem:
Under certain conditions, including extreme voltage and temperature, the peak-peak
voltage may be higher than the specification.
Implication:
Violation of PCI Express Base Specification of the VTX--DIFF-PP voltage. No failures
have been observed due to this erratum.
Workaround:
None identified. Sugar Bay and Bromolow-WS
Status:
For the steppings affected, see the Summary Tables of Changes.
BJ83.
PCIe* Presence Detect State May Not be Accurate After a Warm Reset
Problem:
Under certain conditions, when there is no PCIe device present, the status of Presence
Detect State bit (SLOTSTS Device 1; Function 0,1,2; Offset BAH; bit [6] and/or Device
6; Function 0; Offset BAH; bit [6]) may not be accurate after a warm reset.
Implication:
The Presence Detect State bit may incorrectly report a PCIe device is present even
though no device is actually present, which may result in a system hang.
Workaround:
A BIOS code change has been identified and may be implemented as a workaround for
this erratum.
Status:
For the steppings affected, see the Summary Tables of Changes.
BJ84.
Display Corruption May be Seen After Graphics Voltage Rail
(VCC_AXG) Power Up
Problem:
Powering up the processor graphics logic in the cases of initial poweron or Sx resume
state power up may cause a nondeterministic state in the processor graphics logic.
Implication:
This erratum may cause improper 3D rendering and may result in display corruption.
Workaround:
A graphics driver workaround has been identified and may be implemented as a
workaround for this erratum.
Status:
For the steppings affected, see the Summary Tables of Changes.
