Hi,

after updating a custom build Linux Kernel from 4.0.8 to 4.1.4 my
system fails to attach an MTD partition. Note, that everything worked
fine with Linux Kernels before 4.1.

The error message is:
	ubi_wl_get_peb: Unable to get a free PEB from user WL pool
	autoresize: cannot auto-resize volume 0

The MTD partition has a size of 36 MB. The UBIFS image is created with:
	mkfs.ubifs -v -F -m 2048 -e 124KiB -c 264 -d user -o user.ubifs

The UBI image is created with:
	ubinize -v -o data.ubi -m 2048 -p 128KiB ubinize.ini

ubinize.ini:
    [user]
    mode=ubi
    image=user.ubifs
    vol_id=0
    vol_type=dynamic
    vol_name=user
    vol_flags=autoresize


It works, if I replace the vol_flags with vol_size=32480KiB. But that's
not a final solution for me.

Any idea what is wrong here?

Best regards
Jörg Krause
