Second CPU not registering on 686 SMP kernel

Asked by jason

I just downloaded a copy of Ubuntu 6.06 LTS Server, and did a LAMP install on my server which is an old Compaq Proliant 1600 (which has 2 P3 550mhz processors). Using the
cat /proc/cpuinfo | grep -i '^processor' | wc -l
command I could see that it was only detecting one of the processors (at 550mhz) instead of two. I figured this must have been because it wasn't running an SMP kernel so I used apt-get to install the latest 686 SMP kernel. Unfortunately, I still get the same output when I do a "cat /proc/cpuinfo" which says only 1 processor is detected. Now, I'm pretty sure the processor is running normally, as it is picked up during POST by the BIOS and it shows up in the LCD display on the front of the box but I cannot get it to show up within ubuntu.

The only thing I can think of is that I need to use a different kernel because my processors are obviously very old. Could anyone help me out with how to get this work?

Strange, the i686 should work.
Can you check what the kernel says about it? dmesg, /var/log/syslog, /var/log/kern.log etc.
Can you also post your kernel version with uname -a?

I am a bit of a linux noob so forgive me if I'm not giving you all the right information hehe. Alright, well dmesg seems to just be full of "psmouse.c: bad data from KBC - timeout" messages which seems to be appearing many times a second. The same thing shows up in syslog and kern.log

My kernel version is 2.6.15-28-686 #1 SMP PREEMPT May 10th 2007 i686 GNU/Linux

Jason,
    It is probably best to just perform a fresh reeboot, and post the entire contents of dmesg, so we can take a look. It does look like your kernel version should see both CPUs....

Hi, sorry it's taken awhile to respond, I've been a bit busy. I can't make heads or tail of the dmesg (being new to to linux and all), so I'm not sure where to look.

Well, the problem seems to be this:

SMP motherboard not detected.

Have you made the necessary hardware (jumpers, etc.) and/or software (System Configuration Utility (available on the SmartStart CD) etc.) settings you have to do on this motherboard to enable the two processors?
Perhaps the firmware needs to be updated?
Also make sure the BIOS is set correctly, for instance I would also set your lapic (dmesg complains about Local APIC disabled by BIOS).

jason (butters1) said : 		#6

It seems weird that it isn't detecting an SMP motherboard, because it does detect both processors during the BIOS POST. Unfortunately I don't have a copy of the SmartStart CD (my old work was throwing this server away and I took it), I can't figure out how to get into the BIOS. I'm assuming because its compaq they have some sort of proprietary button you have to press as DELETE isn't working.

I don't really want to download the SmartStart CD (apparently HP want you to pay to do it), so I'm gonna try some of the other software on the HP site.

Okay, I managed to find a SmartStart CD that I already had, it was hiding in a pile of legacy SCSI drivers grrrrr from an old server. I also found another website about installing Debian based OS on the Proliant 1600:

http://www.crazysquirrel.com/computing/debian/servers/debian-on-a-compaq-proliant-1600.jspx

Apparently in the System Configuration if the Operating System is set to "Other" then it will hide the second CPU from it, so all I had to do was set the OS to "Linux" (under Unix) in the Compaq System Configuration and it has detected the second processor fine.

Thanks alot for the help.
