ubi_wl_get_peb: Unable to get a free PEB from user WL pool

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
