Weird. Can you do the following:
(1) use (asdf:traverse 'asdf:load-op :your-system)
 to identify the first few things that get recompiled
(2) use (asdf:input-files 'asdf:whichever-op '("sb-whatever" "component-name"))
 and (asdf:output-files 'asdf:whichever-op '("sb-whatever" "component-name"))
 to see what are the files involved, and
(3) use ls -l to check the timestamps of all said files

One thing that could have gone wrong is that somehow
during your SBCL installation, timestamps were not preserved,
and some .lisp file got a timestamp later than the corresponding .fasl.

Another thing that could have gone wrong is that somehow
your output-translations configuration fails to specially treat
the sbcl contribs.

Or then again, it could be a bug in ASDF that I missed because I've
been using for months the "no ASDF for contribs at runtime" patch
that was just included in the latest SBCL release. But I'm pretty sure
I faced that issue earlier and that it was working
when I released ASDF 2.27.
