Okay, that indicates the ATA commands are being sent not by the kernel
but by some program.  I'm not sure how you can easily find out which
program; probably the best thing to do is turn them off one by one until
you find the one responsible.

I can hardly imagine which user-space tools other than powertop can
interfere here.
Any ideas?

No.  Especially since I have no idea what programs are running on your 
computer.
