60 Specification Update
AR105 Benign Exception after a Double Fault May Not Cause a Triple Fault
Shutdown
Problem: According to the Intel® 64 and IA-32 Architecture Software Developer’s Manual,
Volume 3A: System Programming Guide, if another exception occurs while attempting
to call the double-fault handler, the processor enters shutdown mode. However due
to this erratum, only Contributory Exceptions and Page Faults will cause a triple fault
shutdown, whereas a benign exception may not.
Implication: If a benign exception occurs while attempting to call the double-fault handler, the
processor may hang or may handle the benign exception. 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.
