AM104 Benign Exception after a Double Fault May Not Cause a Triple Fault Shutdown
Status: According to the Intel® 64 and IA-32 Architectures Software Developer’s Manual,
Volume 3A, “Exception and Interrupt Reference”, 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.
Status: 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.
Status: None identified.
Status: For the steppings affected, see the Summary Tables of Changes.
