    Hi again,

    I would like to see from were these higher order allocs comes from.
    Please insert something like this:

    printk("pid=%d; __alloc_pages(gfp=0x%x, order=%ld, ...)\n",
    current->pid, gfp_mask, order);
    show_trace(NULL);

    (You have something resembling the first line - I added this in the beginning
    of __alloc_pages, you may add it together with the error message)
    If everything is ok (correct Symbols.map) you should be able to get
    a symbolic call trace in /var/logs/messages
    (some are false positives, but they can be filtered out manually)
