Well there's another bug report up-list.  "next-20081209: pdflush: page
allocation failure (xfs)".

The clearing of (__GFP_WAIT | __GFP_IO) will call the page allocator in the
weakest possible mode and will of course spew page allocations warnings
with great frequency.  It should at least add in __GFP_NOWARN.
