Hey there!

Traced back that file. That line runs page_buffers(), which launches a bug if
PagePrivate is false. 

#define page_buffers(page)                                      \
        ({                                                      \
                BUG_ON(!PagePrivate(page));                     \
                ((struct buffer_head *)page_private(page));     \
        })

What application were you running, if I may ask?
