note that we turned off debugging a few weeks back. 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. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Closing. Must be long gone by now.....
