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)
