That is very likely my bug.
Do you have the message that should be printed right above the bug ? ( printk(KERN_ERR "mapcount %d page_mapcount %d\n", mapcount, page_mapcount(page)); )
Do you get any errors if building with CONFIG_DEBUG_VM and CONFIG_DEBUG_VM_RB ?
Does it go away if you revert "mm: avoid taking rmap locks in move_ptes()" (cc0eac2e50f036d4d798b18679ca2ae3c4828105 in the -next version I have here) ?
