This is the output of dmesg when i insert my SD card.
the partition mmcblk0p1 is FAT16 mmcblk0p2 is ext2.
mmc0: host does not support reading read-only switch. assuming write-enable.
mmcblk0: mmc0:b368 SD 249856KiB
mmcblk0: p1 p2

The used kernel is 2.6.17-h1940 (i try with a previous version).
fsck -yf doesn't show any file system error.
the failure is not occasional.
should i try with a different sd card?
tanks a lot for your answer.
