I'm using oprofile 0.9.7.
Only CPU samples are available for opreport after dumping:
$ opreport --symbols warning: /no-vmlinux could not be found.

And the kernel:
$ uname -a Linux s136148.plt.kgb.cm4 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
This is a RedHat system:
$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.4 (Tikanga)
There is an oprofile module after initialization:
$ lsmod | grep oprofile oprofile 144785 1
And these are the dmesg messages:
$ sudo opcontrol --start-daemon --no-vmlinux Using 2.6+ OProfile kernel interface. Using log file /var/lib/oprofile/samples/oprofiled.log Daemon started. $ dmesg | tail -n 5 bonding: bond0: first active interface up! bnx2: eth1 NIC Copper Link is Up, 1000 Mbps full duplex bonding: bond0: link status definitely up for interface eth1. oprofile: using NMI timer interrupt. oprofile: using NMI timer interrupt.
Btw, I debugged the Java agent, which shows the following messages:
