:Hello Fellow FreeBSD Users;
:
: I'm somewhat new to FreeBSD. I've been having trouble setting up "SMP"
:under FreeBSD. I compile my kernel with all the Default settings for SMP,
:and when I do so, my machine freezes at "switching to wd0s1 or wd0s2"
:everytime I load the kernel. when I use a generic kernel i'm fine, but when
:I use the kernel with SMP and APIC it freezes. Once a "blue moon" it will
:load and when it does, if I switch to a VC in Xfree86, my computer freezes
:every time.
: Could someone please tell me what to do to stop this.??
:
:Here are my system specs;
:
:FreeBSD 3.2 (this also happens to me on 3.0)
:MotherBoard: PCCHIPS dual PII Motherboard 233-333MHZ
:CPU's: INtel 333Mhz x2
:..
:note: whenever I set my CPU_type for only "I586_cpu" I get a kernel panic.
:could someone plz tell my why?? Also, if I do get a kernel panic, how do I
:"switch Back" to the GENERIC kernel without a bootdisk?? In 3.2 I'm
:clueless??
A pentium-II cpu uses a Pentium-PRO core, not a pentium core. In
otherwords, those are I686_cpu's you have, not 586's, so you should
specify both the I586_cpu and the I686_cpu options.
:# To make an SMP kernel, the next two are needed
:options SMP # Symmetric MultiProcessor Kernel
:options APIC_IO # Symmetric (APIC) I/O
:# Optionally these may need tweaked, (defaults shown):
:#options NCPU=2 # number of CPUs
:#options NBUS=4 # number of busses
:#options NAPIC=1 # number of IO APICs
:#options NINTR=24 # number of INTs
Try specifying the NCPU option specifically. That's all I can think of
right offhand.
options SMP
options APIC_IO
options NCP=2

:thanks :)
