Unmounting local filesystems...

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
