Yes; this is becase the linux-yocto seems to not have been updated to > 3.10.13; so in fact it is failing to build to avoid people to trigger the deadlock. The change which introduces this in lttng-modules is: http://git.lttng.org/?p=lttng-modules.git;a=commit;h=2aecb9b1cbb63f6c524ad9195d8fd06299ef9296 I can update this patch as 2.3.3 has been released and it includes the 3.12 fixes but please check when linux-yocto will be updated so we can fix it.
