You'd need to determine whether the CPU is busy or idle when this is happening.
If it's busy, profile the kernel:
- boot with "profile=1" on the kernel command line
- readprofile -r <do something> readprofile -v -m /boot/System.map | sort -n +2 | tail -40
It it's not busy, then:
while true do ps axl | grep ' D ' sleep 1 done & <do something>
