[yocto] trouble using a local kernel repo

[Hollis Blanchard]

I'm trying to figure out how to use a cloned/modified copy of the 
linux-yocto-3.0 git repository. Here's what I did:

* cloned linux-yocto-3.0.git and committed to the meta branch
* specified my new repo:

--- a/meta/recipes-kernel/linux/linux-yocto_3.0.bb
+++ b/meta/recipes-kernel/linux/linux-yocto_3.0.bb

  PR = "r3"
  PV = "${LINUX_VERSION}+git${SRCPV}"

-SRC_URI = "git://git.yoctoproject.org/linux-yocto-3.0;protocol=git;nocheckout=1;branch=${KBRANCH},meta

  COMPATIBLE_MACHINE = "(qemuarm|qemux86|qemuppc|qemumips|qemux86-64)"

* bitbake -c clean virtual/kernel&&  bitbake virtual/kernel


What I get is this:
ERROR: Function failed: do_validate_branches (see 
/mnt/poky.git/build/tmp/work/beagleboard-poky-linux-gnueabi/linux-yocto-3.0.18+git2+7af8d6f8769335b79c1b76c8bded256b8f909c74_1+368e38c673ffac8b37fc2a2d4c1e4a1e6f8abf19-r3/temp/log.do_validate_branches.5342 
for further information)

There is no more information in that file. It contains only the exact 
message I already got on the console ("ERROR: Function failed ...").

What am I missing? 
http://www.yoctoproject.org/docs/current/kernel-manual/kernel-manual.html was 
not helpful.

Thanks!
