That sounds like it.  I saw the same on a laptop set up as a motion
camera with SD card for the image storage.  I seem to recall the
problem is electrical, and so the impact varies across the population
of XO-1.  There isn't a quirk in the firmware setup.  A quirk might be
placed in the Linux driver to reset the card.
