Have you had the chance to look into this? If so, did you find anything more out? I have noticed the same problem with my Cowon D2 4GB + 8GB SDHC card. (Sandisk Ultra II SDHC 8 GB to be exact.) I have no problems actually using it, but I get these nasty looking messages in dmesg. And just as you said, I get none of those errors if I use the card with a plain SDHC reader, so it would seem that it's not the partition table on the card that is wrong. On the other hand, I would imagine that repartitioning the card to match the size reported when used through the D2 would work around the problem, and I think I'll just take that easier route myself as it seems that most likely it's a problem with the D2 firmware, and then submitting a ticket in their support system may be all one can do.
