Hi
We have i.Mx35 based embedded system running Linux 4.14. The distribution
is built using yocto (rocko branch). Before we moved on to Linux 4.14 we
used Linux 2.6, distribution was again built using yocto(danny branch).
After upgrade to rocko and linux 4.14, we see some error messages on the
console on executing blkid. These messages appear for the SD card. Error
messages appear only if SD Card is mounted and if the start sector for sd
card is 129 or more, doesnt appear is start sector is 128 or less.
Error Message:
root@ebboard:~# blkid
[ 8707.475004] attempt to access beyond end of device
[ 8707.479894] unknown-block(179,0): rw=0, want=1953793, limit=1953792
[ 8707.488054] Buffer I/O error on dev mmcblk0p1, logical block 244207,
async page read
fdisk output:
root@ebboard:~# fdisk -ul
Disk /dev/mmcblk0: 1000 MB, 1000341504 bytes
4 heads, 16 sectors/track, 30528 cylinders, total 1953792 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 129 1953791 976831+ 6 FAT16
If anyone has any idea as to why these warnings are printed depending on
whether the start sector is > 128 would be very much helpful. Thanks.
Regards
Nikhil

Maybe kernel returns incorrect size for the device, or it's blkid bug.
Can you try
LIBBLKID_DEBUG=all blkid -p -o udev /dev/mmcblk0p1
or for /dev/mmcblk0 (not sure if kernel reports it for whole-disk
probing or for the partition).
util-linux version ? (blkid -V).
