Err, I mean, the buffer is large enough. I do not believe there is a
stupid bug like too small buffer. This code has worked for years and I
do not think it was changes much.

The oops may be cause by memory corruption - some of your drivers may
corrupt memory. You need to spend more time debugging this carefully.

Do you have fastmap UBI feature enabled?
