is the system under any load if you run top ?
if not, can you try this..
1. boot with profile=1
2. after its booted, echo > /proc/profile
3. wait a few seconds
Something else to try.. (make sure oprofile is installed, and then..)
opcontrol --start --no-vmlinux
<wait a few seconds>
(all the above needs to be tried as root)
