You didn't by any chance upgrade user-land (the installation
binary sets) without upgrading the kernel first, so you ran the
1.4.1 kernel while doing the above copying?

Well, the fix mentioned above is obviously part of the kernel, so
you'd have to install it to get it ;-)

BTW, it's often a necessity that whenever you upgrade a machine
to first upgrade the kernel, then the user-land.  While you can
usually get by on "point" releases without doing so, it's usually
a good idea to follow this practice anyway.
