It's better if you can post your entire kernel recipe, and what
branch/release you are using.

There are steps that move the kernel source into work-shared, so that
may be impacting your flow.

But the question has to be asked. Why exactly are you manually fetching
the kernel ? The fetcher can take care of most everything.

If you need to modify the source directory later, have a look at the
steps that I'm taking in kernel-yocto.bbclass, since that works properly
within the fetcher and build infrastructure.
