Hello, Here is the problem I'm having: The motherboard temperature keeps getting higher (easily reaching over 50°C in some minutes) after booting when a smp kernel is loaded, even if the machine is almost 100% idle. With an up kernel, the temperature gets down to under 40°C some minutes after the booting. The kernel configuration is identical except for the smp related options. I include below one of the configuration files I have already tried. It's based on /usr/src/sys/i386/conf/GENERIC not on SMP-GENERIC (or a similar one). For some reason my distribution dosen't contain such a file. # FreeBSD: src/sys/i386/conf/MYKERNEL_SMP 2000/08/25 machine i386 cpu I686_CPU ident MYKERNEL_SMP maxusers 32 options NFS_NOSERVER options INET #InterNETworking options FFS #Berkeley Fast Filesystem options FFS_ROOT #FFS usable as root device [keep this!] options MSDOSFS #MSDOS Filesystem options CD9660 #ISO 9660 Filesystem options CD9660_ROOT #CD-ROM usable as root, CD9660 required options PROCFS #Process filesystem options COMPAT_43 #Compatible with BSD 4.3 [KEEP THIS!] options USERCONFIG #boot -c editor options VISUAL_USERCONFIG #visual boot -c editor options KTRACE #ktrace(1) support options SYSVSHM #SYSV-style shared memory options SYSVMSG #SYSV-style message queues options SYSVSEM #SYSV-style semaphores options P1003_1B #Posix P1003_1B real-time extentions options _KPOSIX_PRIORITY_SCHEDULING options ICMP_BANDLIM #Rate limit bad replies options EXT2FS options INCLUDE_CONFIG_FILE options SMP options APIC_IO options NCPU=2 # the values are those shown by options NBUS=3 # mptable. options NAPIC=1 # options NINTR=24 # device isa device pci # Floppy drives device fdc0 at isa? port IO_FD1 irq 6 drq 2 device fd0 at fdc0 drive 0 # ATA and ATAPI devices device ata0 at isa? port IO_WD1 irq 14 device ata1 at isa? port IO_WD2 irq 15 device ata device atadisk # ATA disk drives device atapicd # ATAPI CDROM drives device atapifd # ATAPI floppy drives device atapist # ATAPI tape drives options ATA_STATIC_ID #Static device numbering options ATA_ENABLE_ATAPI_DMA #Enable DMA on ATAPI devices # atkbdc0 controls both the keyboard and the PS/2 mouse device atkbdc0 at isa? port IO_KBD device atkbd0 at atkbdc? irq 1 device vga0 at isa? # splash screen/screen saver pseudo-device splash # syscons is the default console driver, resembling an SCO console device sc0 at isa? # Floating point support - do not disable. device npx0 at nexus? port IO_NPX irq 13 # Serial (COM) ports device sio0 at isa? port IO_COM1 flags 0x10 irq 4 device sio1 at isa? port IO_COM2 irq 3 device sio2 at isa? disable port IO_COM3 irq 5 device sio3 at isa? disable port IO_COM4 irq 9 # Parallel port device ppc0 at isa? irq 7 device ppbus # Parallel port bus (required) device lpt # Printer # Pseudo devices - the number indicates how many units to allocated. pseudo-device loop # Network loopback pseudo-device ppp 1 # Kernel PPP options PPP_BSDCOMP #PPP BSD-compress support options PPP_DEFLATE #PPP zlib/deflate/gzip support options PPP_FILTER #enable bpf filtering (needs bpf) pseudo-device tun 1 # Packet tunnel. pseudo-device pty # Pseudo-ttys (telnet etc) pseudo-device gzip # The `bpf' pseudo-device enables the Berkeley Packet Filter. # Be aware of the administrative consequences of enabling this! pseudo-device bpf #Berkeley packet filter #I2C device smbus device iicbus device iicbb device intpm device smb The version of FreeBSD is 4.0 RELEASE, installed on the second partion of the ide drive.
