Hello,
In My POWER system, I saw 2 new ASSERTs when I ran the xfstests (071 and
087) on 2.6.38-rc4 that I did not see in 2.6.37.
I did a git bisect and the following commit is the one causes the ASSERT
when 071 was run (still working on git-bisect of 087).
Note that the 512 byte sectors warning is printed when the pagesize is
64K. That message is not printed when I change the pagesize to 4K, but
the ASSERT still trips.

xfs: dynamic speculative EOF preallocation
Currently the size of the speculative preallocation during delayed
allocation is fixed by either the allocsize mount option of a
default size. We are seeing a lot of cases where we need to
recommend using the allocsize mount option to prevent fragmentation
when buffered writes land in the same AG.

and here is the log
