Title: [SP9853i] New VMM Instability Detected in Build 1H10 sp9853i 1h10 vmm new

Description: A new anomaly regarding the Virtual Machine Monitor (VMM) has been identified on the SP9853i platform while testing the 1H10 release candidate.

Details:

Summary: During the validation phase of the 1H10 build on the SP9853i unit, the VMM failed to initialize correctly, resulting in a system hang. This behavior is a regression from previous builds and requires immediate investigation by the architecture team.

Steps to Reproduce:
