308 Processor Stall in C1 Low Power State
Description
Under a highly specific set of internal timing conditions, an L3 eviction may stall for a processor core
that has entered the C1 (halt) state. If the processor core has already entered the low power state and
the CpuPrbEn bit in the C1 SMAF is 0b (F3x84[24]), the stall persists until the processor core comes
out of the low power state.
Potential Effect on System
The system may hang.
Suggested Workaround
Contact your AMD representative for information on a BIOS update.
