getting oprofile out of timer mode

[Andrei L. <ali...@cs...>]

Hello,

We are trying to use the Oprofile tool (for a class project), and we
have the following problem: if we try to specify events to profile
(e.g. --event=3DDATA_MEM_REFS), the program says it's in the Timer Mode.
The Oprofile FAQ tells us to add the "lapic" boot option in this case
(we use Pentium III, which should have hardware counters), but doing
so does not change anything for us. Oprofile still starts in the Timer
Mode. Could there be any other reasons for this?

The corresponding line in our grub config file looks like this:
kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=3DLABEL=3D/ rhgb quiet selinux=3D=
0 lapic

Thanks,
Andrei
