  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 inclu= de the verbose logs of the session daemon&n= bsp;by
launching it with the '-vvv' switch.
Als= o, please check that your lttng-modules version&= nbsp;matches the rest of
