[yocto] linux: having problems forcing a kernel recompile...

Hi,
I'm working with the latest poky master branch (as of this morning:
876370419a), and I can't force a recompile of the kernel:
$ bitbake virtual/kernel -c compile -f
fails with
| make[2]: *** [prepare3] Error 1
I have seen this with both linux-qoriq and my own derived linux-yocto
recipe.
I believe it's due to my sysroots kernel source directory not being clean.
When I initially bake my kernel, I can see that the do_populate_sysroot
task is run and it copies a .config into
sysroots/<machine>/usr/src/kernel.
When I try to force the recompile, MAKE sees that my source directory
isn't clean and quits ( throws the prepare3 error ).
Somewhat related, I also notice that neither a
$ bitbake virtual/kernel -c cleansstate
nor a
$ bitbake virtual/kernel -c cleanall
actually cleans my kernel source directory. Should it?
If these are legitimate bugs, I'll be happy to file a bugzilla report.
Thanks
Bob
