Comment:

 Seems to basically work in 406.7.  The contents needs verification, for
 example:

 ec-version returns all blanks; this seems wrong.
 board-revision-int returns a couple blank lines
 dma-ranges returns blanks

 For some examples.

 If the uuid is correct, then at least we can lower this to high from
 blocker.
