[ltt-dev] [Lttng] Need help in running the Lttng on ARMv7 hardware with linux kernel

Hi All,

I am trying to run lttng on ARMv7 target with the following
Kernel --- linux kernel and
Lttng Kernel Patch --- patch-
Modules --- lttng-modules-0.19.1.tar.bz2
Control Modules --- ltt-control-0.88-09242010.tar.gz

Whenever i enable the statedump ( by loading the ltt-statedump module) and
run lttctl tracing ( lttctl -C -w /tmp/trace trace ),
immediately a log "LTT Statedump end" is thrown.

After which i can still see some trace data being accumulated in the trace
path (/tmp/trace).

Now if i close the tracing (lttctl -D trace) & try to view the trace using
lttv-gui, It gets terminated with segmentation fault error.

Can anyone help in letting me know where i am doing wrong.
Also, is there any means to trace only a particular module instead of entire

Thanks in advance :)
