Mathieu, Unfortunately, I think I'm stuck on this version. I have linux version 2.6.30 as a base, this is what Freescale ported to the platform I am using. My understanding is that 0.12.20 is the highest version which supports trace version 2.3. I have version 0.159 of LTTng - I believe that this is the highest version supported by 2.6.30 (tho I can't recall why I think that, as the compatibility matrix says I should be able to go up to 0.170)
Given that I need to be on Linux 2.6.30 - what are my best versions to be using?

LTTV 0.12.20 is quite old though. There might be bugs in it that were fixed since then. Can you try gathering a trace with the latest LTTng version and try to view it with LTTV, so we can figure out if the problem is still there before we start looking for it ?
