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).
