Problem with OProfile on Redhat enterprise 5 with 2.6.18-8.el5

[Eiman E. <eim...@gm...>]

Hi,

I have oprofile 0.9.2 on red hat enterprise 5 running a 2.6.18-8.el5 kernel.
Oprofile was running fine until I installed Vtune 9.0u1 from intel on this
core2 machine. Suddenly I don't get any samples from any profiles I run
using OProfile any more and nothing else has changed on this machine. Does
anyone have any idea why this might hava happened?

Thanks,
 Eiman
