Bad md5sum for linux-2.4.21.tar.bz2 in kernel-2.4.21-4.EL.src.rpm and 9.0.1.EL

[Jacob Rief]

Hi,
I am wondering, but checking the subpackages from the src-rpms
kernel-2.4.21-9.0.1.EL.src.rpm and kernel-2.4.21-4.EL.src.rpm gave me
the following md5sum for the vanilla kernel:

rpm -qp --dump kernel-2.4.21-9.0.1.EL.src.rpm |grep linux-2.4.21.tar.bz2
linux-2.4.21.tar.bz2 28599610 1063820719
bc89effc6f0eefa34c140f25e12880e1 0100644 root root 0 0 0 X

and the same for

rpm -qp --dump kernel-2.4.21-4.EL.src.rpm |grep linux-2.4.21.tar.bz2
linux-2.4.21.tar.bz2 28599610 1063820719
bc89effc6f0eefa34c140f25e12880e1 0100644 root root 0 0 0 X

but the official kernel-2.4.21 from www.kernel.org has an md5sum of 
f51e12efa18bb828cf57d9d4a81b2fb1
I also checked the signature there.

What's wrong?
