  In fact, I made some changes in lttng toolchain(module/tool/ust) to support older kernel/OS.These changes are OK for Lttng 2.6 .Since you are sure "enable-event -k -a" has no problem,it's more chance that I made some inappropriate changes.

Make sure you include the verbose logs of the session daemon by
launching it with the '-vvv' switch.
Also, please check that your lttng-modules version matches the rest of
the toolchain (v2.7.x)

Thanks!
