Very strange that you are getting the _same_ md5 problem! That is really
weird. I don't know how to debug this. If I do a wget locally (I have to
try this from home as well) I get a correct download and can install the
exact same kernel. 

Hmmmm, I do have a machine that sometimes will do something similar. I
think it is some kind of sporadic motherboard problem related perhaps to
the network interface - when yum-installing a very large package
(~530Mbytes) I would sometimes get a cpio error when yum tries to
install it. _Copying_ it manually from an nfs mount and then using rpm
would succeed. Very strange. Maybe related to the problem you are
having? (I know, I know, very very unlikely that hardware is the
problem...). 

Do you have another machine you could use to download the package?
