Can you add "#define DEBUG" as the first line in 'lib/lmb.c'? That should give you debug output when lmb is used. The lmb code works by getting the RAM size, adding reserved areas and then only allowing allocations in non-reserved areay. However, the RAM size is not fully used depending on some config options and/or environment variables. There's possibly something wrong in your configuration around that.
