It is important to find out for sure if this failure is
specific to CPU_IDLE, or it if the root cause existed
before CPU_IDLE, but perhaps was just hidden.
please boot a CONFIG_CPU_IDLE=n kernel
with processor.bm_history=0
to see if the non-cpuidle kernel can also fail.
This will make it more aggressive about entering C3,
and that should be reflected in
/proc/acpi/processor/*/power
Or, if you have USB devices plugged in, you might try
unplugging them to reduce the bus master history interference
and enter C3 more to stress it more.
