Not sure if my comments will fix it,

I'm facing the exact same problem after switching to the MMC driver included in the R4 patch
for the LPC313x kernel from NXP.

I will make some tests to discover what's wrong, if I fix it I will tell you.

hi Stuart,

    its Casper/Kasper whichever... Nolan is my colleague, he forgot to put my name instead..
    Anyway, i do have enough (free) space, i have 1GB SD card and the Root Filesystem only taken up 250MB. I also mount the card on an Ubuntu laptop with SD card reader and i think its OK (i guess!), since i dont see any warning and i could mount, umount, copy, delete,etc... But im not really sure, because this is not a brand new card, i once use this card for my old camera. Is there any tool i can use to fully test my SD cards integrity or something? as i am not familiar with any tools for SD card.
    I may try Miguel's idea first and if i got the same problem then i may purchase a new SD card for further testing...

Hi Casper (Nolan?),

You need to worry about these messages.  Make sure you have free space
on the device.  Also mount it in another machine (with a card reader)
and check to see that there is nothing wrong with the device itself.

Regards, Stuart
