Cezanne platforms under the right circumstances have a synchronization problem where attempting to enter s2idle may fail if the x86 cores are put into HLT before hardware resume from the previous attempt has completed. To avoid this issue add a 10-20ms delay before entering s2idle another time. This workaround will only be applied on interrupts that wake the hardware but don't break the s2idle loop.
