Yes, it's just this one box. A second has kept world and kernel in sync
and loads both filemon and uftdi normally

For a long time (months?) -DWITH_META_MODE has been part of the build
commands. On the troublesome host I've eliminated that and used
make -j3   buildworld > buildworld.log && make -j4  buildkernel   > buildkernel.log && etcupdate -p > etcupdate.log
but it hasn't changed the kernel/world/modules mismatch.

I didn't know about WITHOUT_REPRODUCIBLE_BUILD and have not set it intentionally.
What's the purpose of the variable? I don't find it in man build...

Thanks for writing!
