Can you try with the patch series found at

http://article.gmane.org/gmane.comp.file-systems.ext4/12962
(Threading is not working for gmane currently so the two patches
you may need are
http://thread.gmane.org/gmane.linux.file-systems/31465
http://thread.gmane.org/gmane.comp.file-systems.ext4/12960
)

I guess mmap and truncate combination can result in we missing pagefault
when we write to second block in the same page. That would mean we may
have to do block allocation in writepage.
