It should be "obvious" but a consequence of this is that SMP and
RAIDframe don't currently mix.

In general, if feature "FOO" doesn't work with LOCKDEBUG enabled, an
SMP kernel using "FOO" is extremely likely to run into trouble; the
most likely symptom is a CPU getting "stuck", eventually leading to a
system hang.
