lttng-modules-dkms 2.6.2-1ubuntu1 (i386 binary) in ubuntu wily

 The LTTng project aims at providing highly efficient tracing tools for Linux.
 Its tracers help tracking down performance issues and debugging problems
 involving multiple concurrent processes and threads. Tracing across multiple
 systems is also possible.
 .
 This package contains the LTTng kernel modules. These provide additional
 instrumentation (not found in the mainline kernel), the ring buffer library,
 the tracer itself, and some additional utilities.
 .
 Installing on kernel versions prior to 2.6.38 might be possible, but has not
 been tested.
