It'd be worth seeing if this is still reproducable at all booting with slub_debug=1 OK. I'll boot that way for the next few days and see what happens.... I've been booting for a couple of days now (sorry, first day I had 'slug_debug' instead of 'slub_debug'), and have seen no reports ...... Changing version to '9' as part of upcoming Fedora 9 GA.
