Nope - USB problem. I suggest you apply this:

--- linux-2.4.0-test10-pre5/mm/page_alloc.c Tue Oct 24 21:34:13 2000
+++ linux-akpm/mm/page_alloc.c Thu Oct 26 23:40:13 2000
@@ -527,6 +527,7 @@
 
         /* No luck.. */
         printk(KERN_ERR "__alloc_pages: %lu-order allocation failed.\n", order);
+ BUG();
         return NULL;
 }
 

and when the kernel crashes, feed the log through ksymoops so we
can see where the failing allocation attempt is occurring.

[ You could put a show_stack(0) in here, but I believe ksymoops
  doesn't understand show_stack() output ].
