is oprofile working on CENTOS 6.0 ?
 

Hi


Â*


I am trying to use oprofile with centos 6.0.


Â*


I know that the debug-info for the kernel is not available,
so I believe I


used the correct switches to account for this.


Â*


here is my script…


Â*


# reset everything


opcontrol Â*Â*--shutdown


rm /root/.oprofile/da*


opcontrolÂ* Â*--separate=kernelÂ* --no-vmlinux


opcontrol Â*Â*--event=CPU_CLK_UNHALTED:100000


opcontrol Â*Â*--start


sleep 5


opcontrol --reset


echo "sleeping now"


sleep 20


opcontrol –stop


# all done – use the data with opreport…


echo " "


echo " "


Â*


Â*


When I run this on a CENTOS 6 machine, the machine hangs.


There is no visible panic on the console nor the serial
port.


This is 100% repeatable. I tried multiple machines.


I am using a DELL 2850.


Â*


Any help would be appreciated.

I did a


Â*


opcontrolÂ* --deinit


and


echo 0 > /proc/sys/kernel/nmi_watchdog


Â*


and then ran the script and
everything seems to work now.
