Dual Processors and SMP

[Skorpio]

Hello all. Nube here, as this is my first post... be gentle.
I've taken the step to Linux, in the form of an HP Kayak XM600. It came with only the single processor and 1 gig of Rambus, and I successfully installed OpenSuse 10.2, and configured. I have since upgraded to dual 933's. Everything runs perfectly with a single 933, but as soon as I add the second processor, I get a black screen. Even when I try a new install off the CD, as soon as I select the option to boot off the CD, it tries to load the kernel and then Black screens again. The Bios sees both processors, so I know that's not the problem. Any suggestions?

try to pass this to your boot CD , acpi=off .

Well I tried all of the options on the install DVD, including "acpi=off", and got the same results on each try. I booted the box using Knoppix, and it immediatly recgonized both processors, booted correctly, and am now posting using this. Any other ideas???

As i know OpenSuSE 10.2 should use the kernel smp when more than one processor is located , for Suse 10.1 was not the case !

but you can try to pass the following argument,

smp

or

kernel-smp .

hope this will be useful .

Since kernel 2.6.18 (which shipped with opensuse I believe) multiple CPUs are automatically configured and used in the default kernel. I would suggest though that as this was a brand new feature you might consider using the newer SUSE 10.3 which runs kernel 2.6.22 and would be a little more refined. There may also be various drivers in 10.3 that you didn't have in 10.2.

I recently built my first duo-core 64-bit system. I had trouble getting the installation started, as it would always hang up when checking the hardware.

I had to use the noapic parameter when booting. I tried the acpi=off parameter (I think) and it still hung up. I may have had the syntax wrong, though.

I have to admit that I am a little confused with the two parameters. Here is some info on them:
SDB:Kernel Parameters for ACPI/APIC - openSUSE

Now, my situation may be different, as it seemed to be a 64-bit problem.

i believe you are using the 64 bit version of openSuSE ?

i believe you are using the 64 bit version of openSuSE ?

I was trying something else. I tried 64-bit versions of CentOS and Ubuntu. I already have Suse (32-bit).

[Skorpio]

No, I'm using the 32 bit. I'm downloading the 10.3 as we speak now, to give that a try.
Appreciating all the help and suggestions...
