That did the trick for me, as well. I had forgotton to comment
out "SMP = 1", and after I did and recompiled, the patch works great.
BUT, I got this while the newly compiled kernel was running, and
the *only* change I mage was commenting out "SMP = 1":

This is the first time in the history of my machine that a kernel
oops has happened. I run a small mailing list (using Smartlist) from this
machine, and hopefully this was just a transient error. =-)
