Errata
AAJ22. Delivery Status of the LINT0 Register of the Local Vector Table May be
Lost
The Delivery Status bit of the LINT0 Register of the Local Vector Table will not
Problem:
be restored after a transition out of C6 under the following conditions
• LINT0 is programmed as level-triggered
• The delivery mode is set to either Fixed or ExtINT
• There is a pending interrupt which is masked with the interrupt enable flag (IF)
Implication: Due to this erratum, the Delivery Status bit of the LINT0 Register
will unexpectedly not be set. Intel has not observed this erratum with any
commercially available software or system.
Workaround: None identified.
For the steppings affected, see the Summary Table of Changes.
Status:
AAJ23. Performance Monitor Event SEGMENT_REG_LOADS Counts
Inaccurately
The performance monitor event SEGMENT_REG_LOADS (Event 06H) counts
Problem:
instructions that load new values into segment registers. The value of the
count may be inaccurate.
Implication: The performance monitor event SEGMENT_REG_LOADS may
reflect a count higher or lower than the actual number of events.
Workaround: None identifed.
For the steppings affected, see the Summary Table of Changes.
Status:
AAJ24. #GP on Segment Selector Descriptor that Straddles Canonical
Boundary May Not Provide Correct Exception Error Code
During a #GP (General Protection Exception), the processor pushes an error
Problem:
code on to the exception handler's stack. If the segment selector descriptor
straddles the canonical boundary, the error code pushed onto the stack may
be incorrect.
Implication: An incorrect error code may be pushed onto the stack. Intel has
not observed this erratum with any commercially available software.
Workaround: None identified.
For the steppings affected, see the Summary Table of Changes.
