Root Cause
Some combinations of processor and memory speeds created a timing issue that resulted in application processors
(APs) being out of synchronization. When BIOS code is executed on APs that are out of synchronization an NMI is
generated.
Corrective Action / Resolution
During Power-on self-test (POST) several milliseconds of delay were added after commands that request all APs to run
the same code. This ensures all APs are synchronized before continuing BIOS execution.
