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?
