Hi,
I'm trying to use LTTng 2.0 on a Pandaboard. After building the latest
tools and modules I tried to run lttng and got following error:
# lttng list -k

Segmentation fault
After investigation I found that the oops happened while installing
lttng-ftrace module. Any help resolving it will be appreciated. My
kernel version is 3.0.
