54 Specification Update
Workaround: This non-synchronization can be avoided by issuing an APIC register read after the
APIC register write. This will force the store to the APIC register before any
subsequent instructions are executed. No commercial operating system is known to be
impacted by this erratum.
Status: For the steppings affected, see the Summary Tables of Changes.
