is oprofile working on CENTOS 6.0 ?
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.

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.
Â*
