The I/O errors, the "automount: inserted" message, the fact that it
shows up on ext3 and ext4, makes it smell very much like a hardware
problem (or possibly a mmc device driver problem).  It could be caused
by a fake mmc card that (if you bought it from a street vendor or some
the micro center discount bin at the checkout counter, try getting a
brand name flash from a reputable source --- you get what you pay
for).

It could be caused by flaky hardware, or a MMC drive; it could be
caused by an MMC driver problem.  It doesn't seem like it's a file
system problem.
