Subject: [ltt-dev] lttctl stop command hangs on ARM926 processor

Ok, do I absolutely need to update the kernel in order to apply the
patchset 0.170 ?
lttng 0.170 seems to correspond to kernel 2.6.31.6 ...

We are using a SDK from a 3rd party and upgrading the kernel would
require more tests on our end.
