While there are other kernel issues going on I decided to try to
investigate the difference in meta mode incremental build results
vs. full rebuild.
I started with head -r320192. This sequence avoids updating
the live kernel (since other problems are being looked into).
Local DESTDIR's are used for installkernel.

=46rom a -r320192 context I did:
svnlite update -r320387 /usr/src
I then used my usual script to do buildworld buildkernel. It updated =
things
in the pre-existing /usr/obj/amd64_clang/amd64.amd64/ . (I cause the
explicit amd64.amd64 deliberately. This is not a cross build.)
I'll note that I've been using /usr/obj/amd64_clang/amd64.amd64/ for
incremental builds for a long time. (This will show up later.)
I then used the script to:
installkernel =
DESTDIR=3D/usr/obj/DESTDIRs/clang-amd64-installkernel-r320192_r320387
I then moved /usr/obj/amd64_clang/ to be /usr/obj/amd64_clang_192_387/ =
for
later potential detailed comparisons. I then redid the buildworld =
buildkernel=20
which produced another /usr/obj/amd64_clang/ but from scratch this time.
I then used the script to:
installkernel =
DESTDIR=3D/usr/obj/DESTDIRs/clang-amd64-installkernel-nothing_r320387
I then did (the D %C avoids date/time text being different):
# ls -lD %C =
/usr/obj/DESTDIRs/clang-amd64-installkernel-r320192_r320387/boot/kernel/ =
> ~/ls_192_387_kernel.txt
# ls -lD %C =
/usr/obj/DESTDIRs/clang-amd64-installkernel-nothing_r320387/boot/kernel/ =

The kernel from the incremental build is larger
(includes more?).
Of this the kernel being a different size would
seem to be a problem. But going in a different
direction that is more detailed (content comparison
spanning all of boot, not just boot/kernel/ ):

So a fair number of .ko files also end up being different
by content for a from-scratch build, not just kernel .
Going through looking at .o files for size and permissions. . .

(So "+" is the from-scratch build again.)
Some are different in size (just a couple of examples are
shown of the many):

Looking also at dates for the above (and any other name matches):

So for the incremental upgrade the module's aacraid.o was
rebuilt but the non-module one was not updated.

In this last case the number of files does not match: the
"May 3" is extra. Again the module's .o was updated by the
incremental build but the non-module one was not.
Some exist only in the -r320192 -> -r320387 incremental build:
(some omitted but incremental builds seem to not clean out old
.o's from prior buildkernel activity in general)

(The somewhat manual process might have put a few extra lines above.)
If any of this is picked up and linked in to kernel it might explain
part of the kernel file size difference:
27479832 - 27307184 =3D=3D 172648 .
I stop with this for now. It seems that as things are that one should
clean out the buildkernel materials at least for some types of build
contexts before doing another buildkernel.
