The root cause is PiSmmCpuDxeSmm driver wakes up APs with HLT mode during S3 resume phase to do SMM relocation.

The solution for this issue is let CpuMpPei driver hook S3SmmInitDone ppi notification. In this notify function, it check whether Cpu Loop mode is not HLT mode.

gUefiCpuPkgTokenSpaceGuid.PcdCpuMaxLogicalProcessorNumber ## CONSUMES
UefiCpuPkg/MpInitLib: honor the platform's boot CPU count in AP detection - If a platform boots such that the boot CPU count is smaller than PcdCpuMaxLogicalProcessorNumber, then the platform cannot use the "fast AP detection" logic added in commit 6e1987f19af7. (Which has been documented as a subset of use case (2) in the previous patch.) Said logic depends on the boot CPU count being equal to PcdCpuMaxLogicalProcessorNumber. If the equality does not hold, the platform either has to wait too long, or risk missing APs due to an early timeout. - The platform may not be able to use the variant added in commit 0594ec417c89 either. (Which has been documented as use case (1) in the previous patch.) See commit 861218740d6d. When OVMF runs on QEMU/KVM, APs may check in with the BSP in arbitrary order, plus the individual AP may take arbitrarily long to check-in. If "NumApsExecuting" falls to zero mid-enumeration, APs will be missed. Allow platforms to specify the exact boot CPU count, independently of PcdCpuMaxLogicalProcessorNumber. In this mode, the BSP waits for all APs to check-in regardless of timeout. If at least one AP fails to check-in, then the AP enumeration hangs forever. That is the desired behavior when the exact boot CPU count is known in advance. (A hung boot is better than an AP checking-in after timeout, and executing code from released storage.)
