Multiple CPU Troubles

hybernate20 · n00b Joined: 22 Mar 2006 Posts: 64

I have a Compaq Proliant 800 Series server that has 2 PIII 500 MHz processors on it. When I boot, the bios tells me that it recognizes both of them, but when gentoo loads, it only recognizes one of them. I have the symmetric cpu thing (I can't remember exactly what the option is) compiled into the kernel, and my max # of CPUs is like 8 or something, so I should have everything I need. Is there somethign that I'm missing? when I do a: cat cpuinfo, it should tell me that I have 2 processors right? and when I do a dmesg, I only see it mentioning one of them. Is there a kernel option or a config file that I am missing somewhere?

Thanks
-Nate

Can you post your kernel config?

Yeah. This is somewhat embarassing to ask, but is there a file that contains all of my kernel options or something? How do I post my kernel config?

I'm going to assume you mean my .config file that is in my linux directory. Since it is so gigantic, I just copied to it my web directory...so, the URL to view it is http://nate.homelinux.net/.config

Sorry if that isn't what you wanted!

Oh, yeah. It's a hidden file in the /usr/src/<your-kernel-source> directory called .config. You may also be able to access it through /proc/config.gz.

Also, please post a complete dmesg output.

Good idea; should have thought of that. And, yes, you were right: that was the file I wanted.

WTF? That ain't the url I posted. It's a bug. That's it: no more open source nonsense. Microsoft is the one for me :wink:

Seriously though, the one you found is what I put in. At least you got the title, anyway.

You know, if that hasn't worked out, you could try forcing the local apic on. Add 'lapic' to the kernel line in grub. I'm not sure how it goes with other bootloaders. It's been ages since I've used anything but grub.

Turns out, I ended up removing the System Config Utilities awhile ago, but I got boot disks for it and I loaded them that way. I couldn't find any of hte options that had been listed, which was slightly disappointing. What is the apic? I have no idea what that is........I probably should too. I do use GRUB though, so once I find out what that means, I'll try it. I also could try a few different versions of the config utility to see if I can find that.
