Can you try with the LTTng 2.0 tool chain?  lttng-modules should work
fine on 2.6.38.


We are about to enter the RC cycle, so 2.0 will become the main
supported version very soon(TM).

Hello, I have test LTTng on my machine for scalability test
My env is 4 x AMD Opteron 6200 (16 cores), which has 64 cores
However, The LTTng cannot log data into Trace more than 23 cores.
(1-23 cores is OK), if you can help us to solve this issue,
that will be a great help, thank you.
