I had some trouble collecting debug o/p with this patch. Because of the
number of printk's the machine was crawling during boot. It was difficult
to read/collect the o/p. So i inserted a hack as follows such that
slab_alloc_page prints only during the failure.(modprobe scsi-driver)

+ if (strcmp(current->comm, "modprobe"))
+	printk(KERN_INFO "%s: cpu=%d, cache_cpu=%p, cache_list=%p\n", __func__, cpu, c, l);

Attached here is the boot log. Let me know if i can provide any other
information.

Thanks
