hi,sir !

Can you explain why my ubifs switch to read-only filesystem when it resume from suspend !

Unmounting local filesystems...
mount: can't find /mnt/ram in /proc/mounts
UBIFS error (pid 1201): make_reservation: cannot reserve 160 bytes in jhead 1, error -30
UBIFS error (pid 1201): ubifs_write_inode: can't write inode 135, error -30
UBIFS error (pid 1201): make_reservation: cannot reserve 160 bytes in jhead 1, error -30
UBIFS error (pid 1201): ubifs_write_inode: can't write inode 442, error -30
UBIFS error (pid 1201): make_reservation: cannot reserve 160 bytes in jhead 1, error -30
UBIFS error (pid 1201): ubifs_write_inode: can't write inode 136, error -30
UBIFS: cannot re-mount due to prior errors
