I guess a kernel profile would be useful.
- Add "profile=1" to the kernel boot command line - Run some workload - In another xterm, do:
readprofile -r sleep 10 readprofile -n -v -m /boot/System.map | sort -n +2 | tail -40
(make sure that you're using the correct System.map for the currently-running kernel).
