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.
