Hmm, that's not exactly what I meant.  The kernel string has a different
time, yes - that's to be expected.  The two rpm's actually have the same
"Build Date: Sat 14 Jul 2012 11:33:03 AM EDT" though, which indicates
that they actually should match up.

It's OK that the Signature dates are different.  That's just when the
PGP/GPG signatures are added at a later stage, and they don't have to
line up.

So since they're from the same build, it's really odd that the buildids
don't match.  Perhaps try "rpm -V kernel-uek kernel-uek-debuginfo" to
make sure that the files are still consistent with the rpm.

I doubt it's upstream -- this seems like purely a packaging issue to me.
 Fedora has gone through those kernel versions, and is even newer now,
but hasn't had this problem.

I see in Fedora's kernel.spec that there's a kludged call to debugedit
to preserve a consistent buildid, so maybe that's broken in uek.
