HSM54.
Problem:
The From-IP for Branch Tracing May be Incorrect
BTM (Branch Trace Message) and BTS (Branch Trace Store) report the “From-IP”
indicating the source address of the branch instruction. Due to this erratum, BTM and
BTS may repeat the “From-IP” value previously reported. The “To-IP” value is not
affected.
Using BTM or BTS reports to reconstruct program execution may be unreliable.

Summary Table of Changes.
Implication:
Status:
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
HSM55.
Problem:
Implication:
Status:
TM1 Throttling May Continue indefinitely
TM1 (Thermal Monitor 1) throttling may continue when the processor’s temperature
decreases below the throttling point while the processor is in Package C3 or deeper.
The processor will continue thermal throttling but does not indicate it is hot.
For the steppings affected, see the
Summary Table of Changes.
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
HSM56.
Problem:
Internal Parity Errors May Incorrectly Report Overflow in The
IA32_MCi_STATUS MSR
Due to this erratum, uncorrectable internal parity error reports with an
IA32_MCi_STATUS.MCACOD (bits [15:0]) value of 0005H and an
IA32_MCi_STATUS.MSCOD (bits [31:16]) value of 0004H may incorrectly set the
IA32_MCi_STATUS.OVER flag (bit 62) indicating an overflow even when only a single
error has been observed.
IA32_MCi_STATUS.OVER may not accurately indicate multiple occurrences of
uncorrectable internal parity errors. There is no other impact to normal processor
functionality.
For the steppings affected, see the
Summary Table of Changes.
Implication:
Workaround:
None identified.
Status:
HSM57.
Problem:
Performance Monitor Events OTHER_ASSISTS.AVX_TO_SSE And
OTHER_ASSISTS.SSE_TO_AVX May Over Count
The Performance Monitor events OTHER_ASSISTS.AVX_TO_SSE (Event C1H; Umask
08H) and OTHER_ASSISTS.SSE_TO_AVX (Event C1H; Umask 10H) incorrectly
increment and over count when an HLE (Hardware Lock Elision) abort occurs.
The Performance Monitor Events OTHER_ASSISTS.AVX_TO_SSE And
OTHER_ASSISTS.SSE_TO_AVX may over count.
For the steppings affected, see the
Summary Table of Changes.
Implication:
Workaround:
None identified.
Status:
HSM58.
Problem:
Implication:
Processor May Run at Incorrect P-State
The processor package may use stale software P-State (performance state) requests
when one or more logical processors are idle.
The processor package may run at a higher or lower than expected P-State. This issue
may persist as long as any logical processor is idle.
For the steppings affected, see the
Summary Table of Changes.
Workaround:
It is possible for the BIOS to contain a workaround for this erratum.
Status:
