Hi ,

I am new to LTTng usage, I am trying to use LTTng 2.0.1 and LTTng-modules-2.0.2  for ARM(omapL138), with Linux kernel 2.6.33 wit RT-29 patch on it.

After enabling all the kernel events I am facing the below errors. I loaded all the modules manually by insmod.

root at arago:~/lttng-traces# arm-none-linux-gnueabi-lttng create newsessiom
Session newsessiom created.
Traces will be written in /home/root/lttng-traces/newsessiom-20110325-154922

root at arago:~/lttng-traces# arm-none-linux-gnueabi-lttng enable-event -a --kernel
All kernel events are enabled in channel channel0

root at arago:~/lttng-traces# arm-none-linux-gnueabi-lttng start
LTTng: Failure to write metadata to buffers (timeout)
Error: Starting kernel trace failed

Please kindly help me on this.

Thanks in advance,
