Hi,
(sorry for posting this to two lists, Reply-To: is set.)
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.
TIA,
Daniel
