Thank you for your suggestion, I tried this ordering, except I added
opcontrol --start-daemon --verbose=3Dall

I did opcontrol --start, saw that it claimed it started profiling in
/var/lib/oprofile/samples/oprofiled.log

I then did some kernel stuff (find /) and then executed opcontrol --dump

This is what was printed in oprofiled.log:
oprofiled started Tue Apr 24 10:19:15 2007
kernel pointer size: 8
Read buffer of 16314 entries.
CPU_SWITCH to 1
Etc....
CPU_SWITCH to 0
Etc...

That is all that is printed until I stop the daemon, when it prints:
Tue Apr 24 10:29:15 2007

Nr. sample dumps: 2
... all samples : 0 after this

Actually, yes, I have, but oprofile 0.9.1 included doesn't recognize my
CPU and so won't work.

Thanks for your help, any other ideas?  I wonder if my kernel isn't
configured correctly for some reason.  It is x86_64, doesn't oprofile
work there?

Would it help if I attached my .config?
