 SHC12900064 booted but stopped with only the XO character showing (no
 progress dots or text).  The keyboard and battery charging are functional.
 Unfreezing the DCON and working over IRC Quozl and I seem to have
 diagnosed an EC/HOST communications failure which needs further
 diagnostics.

 The laptop has Q4B08 installed, and is being kept alive on AC power until
 we come up with something else we think is worth looking at.

 I believe Martin has also occasionally seen an XO fail to boot while stuck
 on an XO, so this could potentially be more than a one-off.
