 This may be unrelated, but I'm successfully using a JetFlash USB stick
 to move small amounts of data between my i386 7.0-CURRENT workstation
 and my amd64 laptop.  So far things seem to work fine, so it may be a
 bug that is not related to msdosfs.
 
 Another thought is that I had similar problems with msdosfs and cd9660
 filesystems when I tried to read their contents from a root shell (which
 doesn't have any LC_XXX or LANG environment vars), especially when the
 filesystem contained Greek filenames.  Setting up the correct locale
 fixed everything.
 
 I'm not saying that nothing is wrong with msdosfs on amd64.  Just adding
 what I've seen so far, in case it helps track down the cause of your
 problems.
