Hello, I had exactly the same problem than you.
Your problem is that /dev/oprofile/0 is missing because the perf counters used by OProfile are already used by the NMI watchdog. The solution consists in disabling the NMI watchdog before trying to use OProfile. The following commands should do the work: opcontrol --deinit echo 0 > /proc/sys/kernel/watchdog opcontrol --init It looks like /proc/sys/kernel/nmi_watchdog has recently be renamed /proc/sys/kernel/watchdog and that the opcontrol script hasn’t taken that rename into account yet. Could you please try the above three commands? BRgds, Lénaïc.
