Hi guys, I tried to shrink the microSD second partition (mmcblk0p2) since my code is just getting a couple of GB.
After shrinking I can manually mount the partition and the file system looks OK.
However, system cannot (auto)mount the partition at boot time.
Looking at the dmesg logs, I found:

[ 2.994746] mmc0: new ultra high speed SDR104 SDHC card at address aaaa
[ 2.996873] mmcblk0: mmc0:aaaa SC16G 14.8 GiB
[ 3.005459] mmcblk0: p1 p2
[ 3.287979] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)
[ 3.410895] EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)
[ 3.428516] EXT4-fs (mmcblk0p2): re-mounted. Opts: (null)
[ 3.436674] overlayfs: "xino" feature enabled using 32 upper inode bits.
[ 3.437396] overlayfs: failed to verify upper (/root, ino=27325, err=-116)
[ 3.438008] overlayfs: failed to verify index dir 'upper' xattr
[ 3.438532] overlayfs: try deleting index dir or mounting with '-o index=off' to disable inodes index.

It seem that the overlays kernel module cannot verify xattr
Do you have any suggestions?

Tnx a lot!
