I've just built a new kernel for a just upgraded box to 4.5-STABLE. I've included NMBCLUSTERS=0 and NBUF=0 to try the auto-sizing feature as documented in LINT The box is P4-1400 with 1.5GB RAM, (not)running: FreeBSD 4.5-STABLE #2: Tue Feb 5 12:18:11 CET 2002 root@atleo5.leo.org:/usr/obj/usr/src/sys/ATLEO5 The kernel does not even boot, because of: [..] real memory = 1610596352 (1572848K bytes) Physical memory chunk(s): 0x00001000 - 0x0009efff, 647168 bytes (158 pages) 0x003a1000 - 0x5fff3fff, 1606758400 bytes (392275 pages) kmem_suballoc: bad status return of 1. panic: kmem_suballoc [..] Now, what I remember it may have to do with some of the tunings failing. I also have maxusers=512 (but this caused no problems until now). Any advice, even "don't set NMBCLUSTERS to 0", preferred with "because in your setup XXXX happens", but greatly appreciated in any way.
