Many thanks for testing.

Could you please verify the crash only occurs with the patch?

Can you provide the vmlinux matching this oops, so I may analyze the
exact null dereferencing point?
It seems to be somewhere in ubi_wl_init, however the patch seems not to
affect these parts of ubi...

Also, what's your CONFIG_MTD_UBI_BEB_LIMIT?

Regards,
Shmulik
