    We do have known issues in XFS on 2.6 with handling certain VM
    allocation failures -- maybe hitting that here. Christoph has
    been looking at making XFS do a better job there; __GFP_NOFAIL
    allocations failing seem to be the worst issue for us - on the
    occasions I've hit that though, its always immediately fatal.

    cheers.
