LTTng - some problem - not able to see kernel traces

Hi:

I am porting LTTng (version info given below) on linux-2.6.18.2 for arm arch.

    LTTng  0.6.41
    LTT Control   0.3.35

No LTTng userspace tracer
No Genevent

I have checked that above config should work from,
    http://ltt.polymtl.ca/svn/ltt/branches/poly/doc/developer/lttng-lttv-compatibility.html

I have applied the kernel patches, compiled and installed ltt-control
on my rootfs. Selected probes options in kernel config as built-in.

This is the output i am getting. I am only interested in getting kernel traces.

Maybe someone can tell me if i forgot to include something or merely
incorrectly trying to use LTTng from command line.

Thanks and Regards,
Naval Saini
