I just noticed that doing a ktrace will cause a vm_page_free panic:
vm_page_free:  offset(46092288), bmapped(0), busy(1), PG_BUSY - freeing busy pg.

Just do a ktrace and then during or shortly after while swapping
it will panic.  Don't do ktrace, system up for long time.
Same ktrace/free bug in today -current and sept 25 -current kernel of mine.

P.S.  I *need* ktrace to debug the stupid ibcs2 emulator (:
