I am building on a Debian/unstable box with a core i7 cpu and 24 gig of RAM.

I have tried taking the pre-baked Angstrom image from here:

  http://www.angstrom-distribution.org/demo/beaglebone/Angstrom-Cloud9-IDE-eglibc-ipk-v2012.02-core-beaglebone-2012.02.14.img.xz

(which works for me), and replacing the uImage on the vfat partition
by copying over the existing one with one I built.  That boots, but the
rootfs isn't aligned (different kernel/module versions?).  

If I then try dropping in my rootfs, by reformatting the ext4fs and
untarring the rootfs tarball I built, I get 0.6 seconds into the boot
and then the boot stalls with some udevd messages, like so:

I don't know what that means, nor where to go from there.
