No. You are using the wrong kernel.

The relevant code section, that throws the error is:

So for this error to trigger, you would have to have revision 3 or later, which you don't,
or you would have to have a kernel without LP support compiled in.

Make sure you installed your kernel _and_ initramfs correctly.
Also make sure to boot the correct kernel.
