Can you use "cpupower monitor"
(tools/power/cpupower)
instead of turbostat.
Then you will also see what idle states the kernel requested.
Does this single job (or something else) produce interrupts frequently (maybe
powertop helps in this respect)?
This would explain why C1 and no deeper sleep states are entered.
If properly configured, "cpupower top" should invoke the powertop tool.
