I've tried 2 different Beagleboards and 3 different cards by 2 different manufacturers, and the problem is repeatable on all permutations. I've put the cards into a card reader on my workstation and done a "dd if=/dev/sdf of=/dev/null" to verify the cards aren't wedged. I've searched for this on Google and found no references, but I cannot believe I'm the only person seeing this - but am I?
