During the installation of the Intel VTune Amplifier XE 2013 build 253325 the OS (ubuntu 12.04.1 LTS) I get the folowing warning: Installing Amplifier XE Sampling driver kit component... WARNING: NMI watchdog timer is enabled. Suggestion: turn off the nmi_watchdog timer before running sampling. When I turn off nmi_watchdog and reinstall, everything looks good, but the Ubuntu 12.04 turn on nmi_watchdog after each restart. After installation of the Intel VTune Amplifier XE 2013 build 253325 ,the Ubuntu 12.04.1 LTS (supported OS) is not able to suspend or hibernate on laptop (ThinkPad T410). After uninstallation Intel VTune Amplifier XE 2013 everything works OK. Is there any workaround how to solve this problem?

There must be something in Intel VTune Amplifier XE 2013 build 253325, what cause this problem on Ubuntu 12.04 (laptop). Coincidence with nmi_watchdog may be insignificant only. Should I report this problem on your premier support site?

- add argument “nmi_watchdog=0” in /boot/grub/grub.conf , then reboot system

Yes. Feel free to submit this issue to Intel Premier, with log files after running "amplxe-feedback -create-bug-report "
