This is normally disabled due to the following issue that's noted in AMD's errata pages:
Quote:
14 Processors with Half-Frequency Multipliers May Hang Upon Wake-up from Disconnect
Products Affected: A4, A5, A6, A7, A9
Normal Specified Operation: The processor should reconnect to the system bus upon wake-up after a disconnect while in the C2 and C3 ACPI low-power states.
Non-conformance:The processor uses a special circuit to wake up from a low-power state and reconnect to the system bus when the nominal operating frequency is generated with a half-frequency multiplier. This circuit is rarely observed to glitch when coming out of the C2 and C3 low-power states.
Potential Effect on System: The system will hang.
Suggested Workaround: Do not use the C2 or C3 ACPI states on processors that run at a nominal operating frequency generated with a half-frequency multiplier. This can be accomplished by having the BIOS not declare C2 or C3 support to the operating system in the Fixed ACPI Description Table (FADT).
Resolution Status: Fix planned for a future revision.
Also note that all Cx states only apply to the CPU, and no other part of the system. For Cx states to operate correctly, there **MUST** be BIOS support.
