Please do note that the above messages are from kernel initialisation
of modules.  This happens either before init is started, or are
triggered by udev, and by their nature will be run in parallel.  This
will take effect irrespective of the CONCURRENCY option, because it's
not being parallelised at the level of sysvinit/rc; there's nothing
we can do in sysvinit to change this, I'm afraid; it's completely out
of our hands.

Roger
