Hi Theodore, thanks for the hints well, i have same board with old kernel 3.5.1 perfectly working, so i can exclude hardware issues. Same for card issues, same card moved on kernel 3.5.1 board behave correctly. Strangely, seems i have "write" issues, if i format the card on PC and put it back on the soc board, i get no errors on fsck. If i format on soc board, and fsck from PC i get errors. I am now moving the discussion to linux-mmc, Regards, angelo On 19/11/2014 14:50, Theodore Ts'o wrote:
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. Regards, - Ted
