Hi Ross,

I took this series, but it resulted in a lot of OOM failures during the
reproducibility test build:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2484
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2485
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2487
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2489
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2486
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2488
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2491
https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2493

Some of these do reports errors in ovmf_git.bb:do_deploy, I wonder if
this is somehow related.

Michael Halstead has some traces from the OOM killer, at least for one
occurrence. I will forward you the mail he sent about these, maybe there
is any useful data in there.

Also, one build completed (to a failure). Maybe just some luck in job
ordering, so it failed before it had the opportunity to crash. It
contains errors for both ovmf and ffmpeg builds:

https://autobuilder.yoctoproject.org/valkyrie/#/builders/37/builds/2492

Also this same build does report some reproducibility issues on clang,
llvm and others:

http://valkyrie.yocto.io/pub/repro-fail/oe-reproducible-20250914-qe46no4m/packages/diff-html/

So, I believe this might a bit difficult to debug, please tell me if I
can help you in any way.

Thanks,
Mathieu
