Errata

2 Duo Processor

Specification Update 21

Workaround: None identified.

Status: For the steppings affected, see the Summary Tables of Changes.

AW9. A REP STOS/MOVS to a MONITOR/MWAIT Address Range May

Prevent Triggering of the Monitoring Hardware

Problem: The MONITOR instruction is used to arm the address monitoring hardware for

the subsequent MWAIT instruction. The hardware is triggered on subsequent

memory store operations to the monitored address range. Due to this

erratum, REP STOS/MOVS fast string operations to the monitored address

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.

AW10. Performance Monitoring Event MISALIGN_MEM_REF May Over Count

Problem: Performance monitoring event MISALIGN_MEM_REF (05H) is used to count

the number of memory accesses that cross an 8-byte boundary and are

blocked until retirement. Due to this erratum, the performance monitoring

event MISALIGN_MEM_REF also counts other memory accesses.

Implication: The performance monitoring event MISALIGN_MEM_REF may over count. The

extent of the over counting depends on the number of memory accesses

retiring while the counter is active.

Workaround: None identified.

Status: For the steppings affected, see the Summary Tables of Changes.

AW11. The Processor May Report a #TS Instead of a #GP Fault

Problem: A jump to a busy TSS (Task-State Segment) may cause a #TS (invalid TSS

exception) instead of a #GP fault (general protection exception).

Implication: Operation systems that access a busy TSS may get invalid TSS fault instead

of a #GP fault. Intel has not observed this erratum with any commercially

available software.

Workaround: None identified.

Status: For the steppings affected, see the Summary Tables of Changes.
