Thanks Peter! That does make testing easier (don't have to rename /bin/mount) Smiles!

I came up with a patch to nash/block.c that seems to fix the problem for me, you're welcome to use it if you want.  I just added another modified function to populate the cache that doesn't probe devices or scan for block id tags (BLOCK_ID_DEV_FIND instead of BLOCK_ID_DEV_NORMAL).
