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.
