Intel® Xeon® Processor E5-2600 v4 Product Family 17
Specification Update December 2016
Integrated Core/Uncore Errata
BDF1 Enabling ISOCH Mode May Cause The System to Hang
Problem: When ISOCH (Isochronous) operation is enabled within BIOS, the system may hang
and fail to boot.
Implication: Due to this erratum, the system may hang and fail to boot.
Workaround: It is possible for the BIOS to contain a workaround for this erratum.
Status: For the Steppings affected, see the Summary Tables of Changes.
BDF2 PCI BARs in the Home Agent Will Return Non-Zero Values During
Enumeration
Problem: During system initialization the Operating System may access the standard PCI BARs
(Base Address Registers). Due to this erratum, accesses to the Home Agent BAR
registers (Bus 1; Device 18; Function 0,4; Offsets 0x14-0x24) will return non-zero
values.
Implication: The operating system may issue a warning. Intel has not observed any functional
failures due to this erratum.
Workaround: None identified.
Status: For the Steppings affected, see the Summary Tables of Changes.
BDF3 PCIe* Header of a Malformed TLP is Logged Incorrectly
Problem: If a PCIe port receives a malformed TLP (Transaction Layer Packet), an error is logged
in the UNCERRSTS register (Device 0; Function 0; Offset 14CH and Device 2-3;
Function 0-3; Offset 14CH). Due to this erratum, the header of the malformed TLP is
logged incorrectly in the HDRLOG register (Device 0; Function 0; Offset 164H and
Device 2-3; Function 0-3; Offset 164H).
Implication: The PCIe header of a malformed TLP is not logged correctly.
Workaround: None identified.
Status: For the Steppings affected, see the Summary Tables of Changes.
BDF4 A Malformed TLP May Block ECRC Error Logging
Problem: If a PCIe* port receives a Malformed TLP that also would generate an ECRC Check
Failed error, it should report a Malformed TLP error. When Malformed TLP errors are
masked, the processor should report the lower-precedence ECRC Check Failed error
but, due to this erratum, it does not.
Implication: Software that relies upon ECRC Check Failed error indication may not behave as
expected.
Workaround: None identified.
Status: For the Steppings affected, see the Summary Tables of Changes.
BDF5 The System May Hang During an Intel® QuickPath Interconnect
(Intel® QPI) Slow to Fast Mode Transition
Problem: During an Intel QPI slow mode to fast mode transition, the LL_STATUS field of the
QPIPCSTS register (Bus 0; Device 8,9,10; Function 0; Offset 0xc0) may not be
correctly updated to reflect link readiness.
Implication: The system may hang waiting for the QPIPCSTS.LL_STATUS to update.
Workaround: It is possible for the BIOS to contain a workaround for this erratum.
Status: For the Steppings affected, see the Summary Tables of Changes.
