I almost located the root cause of oprofile failure. The default event of oprofile sometimes is incorrect in kernel.The event should be 0x3c instead of 0x2e. It looks like oprofiled parses event incorrectly or someone configured user root's /root/.oprofile/daemonrc with incorrect event. Anyway, it could work now.
