Specification Update
range may prevent the actual triggering store to be propagated to the
monitoring hardware.
Implication: A logical processor executing an MWAIT instruction may not immediately
continue program execution if a REP STOS/MOVS targets the monitored
address range.
Workaround: Software can avoid this erratum by not using REP STOS/MOVS store
operations within the monitored address range.
Status: For the steppings affected, see the Summary Tables of Changes.
AI105. False Level One Data Cache Parity Machine-Check Exceptions May be
Signaled
Problem: Executing an instruction stream containing invalid instructions/data may
generate a false Level One Data Cache parity machine-check exception.
Implication: The false Level One Data Cache parity machine-check exception is reported
as an uncorrected machine-check error. An uncorrected machine-check error
is treated as a fatal exception by the operating system and may cause a
shutdown and/or reboot.
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.
AI106. A Memory Access May Get a Wrong Memory Type Following a #GP
due to WRMSR to an MTRR Mask
Problem: The TLB (Translation Lookaside Buffer) may indicate a wrong memory type
on a memory access to a large page (2M/4M Byte) following the recovery
from a #GP (General Protection Fault) due to a WRMSR to one of the
IA32_MTRR_PHYSMASKn MSRs with reserved bits set.
Implication: When this erratum occurs, a memory access may get an incorrect memory
type leading to unexpected system operation. As an example, an access to a
memory mapped I/O device may be incorrectly marked as cacheable, become
cached, and never make it to the I/O device. Intel has not observed this
erratum with any commercially available software.
Workaround: Software should not attempt to set reserved bits of IA32_MTRR_PHYSMASKn
MSRs.
Status: For the steppings affected, see the Summary Tables of Changes.
AI107. PMI While LBR Freeze Enabled May Result in Old/Out-of-date LBR
Information
Problem: When Precise Event-Based Sampling (PEBS) is configured with Performance
Monitoring Interrupt (PMI) on PEBS buffer overflow enabled and Last Branch
Record (LBR) Freeze on PMI enabled by setting FREEZE_LBRS_ON_PMI flag
(bit 11) to 1 in IA32_DEBUGCTL (MSR 1D9H), the LBR stack is frozen upon
