I tried somthing similar, works fine:

	$ dd if=/dev/random of=/dev/null bs=64k
	## on another tty
	$ pidof dd # YMMV
	19329

So it seems there is nothing special in name 'dd'. We need more
information. Can you reproduce problem? Can you reproduce problem as
non-root? Does it specific to 'dd'? Can you provide typescript
[script(1)] of how things go wrong on your computer? You use AppArmor.
Does pidof have profile? Is there anything about pidof(1) in AppArmor
logs?
