I have been looking into this and its failing on this section of code sys/vm/uma_core.c:uma_zone_slab if (keg->uk_flags & UMA_ZFLAG_INTERNAL && keg->uk_recurse != 0) if ((zone != slabzone) && (zone != slabrefzone)) return (NULL); I am able to boot now if I add (zone != zones) to the list of checks. This only happens on SMP so is there some race? AndrewReceived on Fri May 11 2007 - 02:35:49 UTC
