Re: [CentOS] is oprofile working on CENTOS 6.0 ?

I did a

opcontrol --deinit

and

echo 0 > /proc/sys/kernel/nmi_watchdog

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

Hi

I am trying to use oprofile with centos 6.0.

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

used the correct switches to account for this.

here is my script...

# reset everything

opcontrol --shutdown

rm /root/.oprofile/da*

opcontrol --separate=kernel --no-vmlinux

opcontrol --event=CPU_CLK_UNHALTED:100000

opcontrol --start

sleep 5

opcontrol --reset

echo "sleeping now"

sleep 20

opcontrol -stop

# all done - use the data with opreport...

echo " "

echo " "

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.

Any help would be appreciated.
