Hi,

lttng-modules officially supports kernel 2.6.38 and up only.

However, there were some experimental patches to make it run on CentOS 6
(kernel 2.6.32), see
http://lists.lttng.org/pipermail/lttng-dev/2012-May/017908.html . Ubuntu
10.04 comes with 2.6.32 if I'm not mistaken, so it might be possible to
make it work using those.


Cheers,
