Hello All,
I have a co-located HP DL360G3 server to which I do not have physical
access. It has 2 x 2.8GHz Xeon CPUs with HTT. One of the ISP's
engineers has confirmed that both CPUs are detected when the BIOS
POSTs.
I have cvsup'd to the latest 5.3R security release and successfully
built 'world', something I have done successfully many times with 4.x
releases, using the instructions from the handbook. I used a custom
kernel configuration which included options SMP and device apic. On
reboot dmesg confirmed that the custom kernel was used, however SMP was
not active and the additional CPUs were not launched.
Thinking that perhaps my custom kernel conf was at fault, I compiled a
GENERIC smp kernel with:
# cd /usr/obj
# chflags -R noschg *
# rm -rf *
/usr/src/# make buildkernel KERNCONF=SMP
/usr/src/# make installkernel KERNCONF=SMP
After reboot the dmesg output is as follows:

I just don't understand why the kernel isn't running SMP. To my mind
it's either something in my method (most likely), a hardware problem,
or something odd in the way 5.3R detects the CPUs on the hardware.
I have successfully compiled SMP kernels on identical hardware with
FreeBSD 4.8R. With the HTT 4 CPUs are launched as they should be here.
Now I think about it I have another machine, a HP DL380 with a single
HTT Xeon processor, which is displaying the same problem.
Thanks in advance.
greg.
