do_root_fs failing on flock command

[Jack Mitchell <ml@communistcode.co.uk>]

I'm attempting to build core-image-minimal using oe-core + 
meta-beagleboard on an NFS mount. I'm running into the following error:

Does anyone have any insight to why this may be failing. It mentions a 
bad file descriptor, so I assume it is related to building on an NFS mount.

Cheers,
Jack.
