I've got oprofile working sort of with 2.6.15 kernel on a 24Kc processor
using just timer interrupts. I only get samples within vmlinux.out
though. When I look at top output during the period of time there is
definitely some significant user mode time. Before digging too deep into
the problem I thought I'd ask to see if this is a known limitation and
if everyone is seeing this.
Thanks,
Kurt Schwemmer

That's the symptom of running too old oprofile tools; you need to use a
cvs; the release tarballs are too old.
