Please make sure to copy me directly, both as the maintainer of the
parts of core in question and the author of the patches.
We've had no reports of issues since any of these went in, and they
aren't exactly a recent change. Which obviously means there's
potentially something different in the environment or the kernel
recipes.
If you get a set of reproducing steps with linux-yocto and core, I
can lend a hand with any fixes.
