You can download a precise amd64 build here:
Please test this with this package and see if systemtap is working
properly.

I hesitate to upload the ddeb as it's comparable to an iso in size. It's
probably faster to rebuild the kernel than download
I've developed a test suite to verify this new part of the build but am not
sure how to integrate it. Attached.

The root cause of the build failure under precise was that we were trying to
assign
an entry to debuglink that didn't exist. When the build was iterating over
kos, it simply expects that the path in /lib/modules will mirror that found
in /usr/lib/debug, this is not always true. There are modules c
Building against precise is interesting, at first we thought (ayan and myself)
that
we were modifying the same object twice which results in an error. To remedy
that, sort -u was added to the processing loop. After another precise build
with that precaution we get this failure.

Got a chance to retest against an officially built kernel and dbgsym, the
technique works, so
now all that's left is to independently verify the entire patch on a new build
and call
it done.

@Chris, this doesn't work.
BTW, you don't have to bounce this back to me to verify, this is
a one line test, either the probed module will return a list of
entry points, or it won't. Also, please provide the main "headers"
package next time, the archive is marching on and deleted the
last build.
