I did a opcontrol --deinit and echo 0 > /proc/sys/kernel/nmi_watchdog and then ran the script and
everything seems to work now. wr From:

Reich 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. wr |
