I just released LTTng 0.193 for kernel 2.6.32.4 which includes patches
fixing these odd per-cpu timer teardowns. The patches concerned are:

lttng transport lockless add timer on works with del timer sync
omap trace clock use del timer sync
x86 trace clock use mod timer
trace clock 32 to 64 use del timer sync

(they are at the end of the LTTng 0.193 tree)

Feedback is welcome,

Thanks,

Mathieu
