If you hit this, yes I'd insert the BUG_ON in your test kernel and fix the code. Maybe add the BUG_ON in upstream for CONFIG_DEBUG or something. Which callers did you see cause this? If it was a common problem I would expect a lot of data corruption or crashes on ia64 systems which I haven't heard of.
