Revision Guide for AMD Family 10h Processors
406 Processor Does Not Perform BmStsClrOnHltEn Function
Description
The processor does not perform a write operation to clear the BM_STS bit when Interrupt Pending
and CMP-Halt Register[BmStsClrOnHltEn] (MSRC001_0055[29]) is set.
Potential Effect on System
The ACPI-defined register BM_STS bit may not be cleared before entry into C1E mode. This does
not cause functional issues but may reduce the power saving effectiveness of message-triggered C1E
mode.
Suggested Workaround
Contact your AMD representative for information on a BIOS update.
