10.2 Has Only Smp Kernel?

I see from the OpenSuse site that 10.2 has gone to the SMP Kernel 2.6.17 only? I've had a problem before when I have tried SMP kernel, either by accident when applying upgrades with Yast (I have SLED 10.0) or when trying other distros. My machine won't shut down with SMP kernels. It only gets to the point where the system halts, but the PC does not shut down. It is a Compaq with a Celeron. Is there something I can do about it?

Thanks!

Yes. Compile your own kernel and change it. Short of that, not really.

You do know that OpenSuse 10.2 is a development disrto and problems like that can be expected.

I see that the kernel is now up to 2.6.18-rc5xx and an update to that was available overnight.

If you are going to use 10.2, you need to be prepared to update on a regular basis -- as the fixes come out.

Of course, you could use the stable 10.1, update it, and have a darn good system.

Have fun...

Just want to point out that as the user stated..from Suse 10.2 onward the SMP kernel will be the ONLY kernel available for EVERYONE. At least that is my understanding.

That is my understanding as well.

based on what? Gut feeling? Any references?
and how do you plan to install smp kernel on non-smp box? and what % of users has smp/hyperthreading capable cpu?

well:
http://search.belnet.be/packages/suse/proj...kotd/i386/HEAD/
has
kernel-default-2.6.18-20060930165317.i586.rpm
standard single cpu kernel.

Taken from the suse 10.2 alpha 4 announcement here:

http://lists.opensuse.org/opensuse-announc...9/msg00000.html

* We switched to kernel 2.6.18rc5 - and use only SMP kernel, the
default kernel is smp, the kernel-smp is now dropped. Now all
kernel module packages (kmp) and the Xen packages have been adopted
for the new kernel.


SMP kernel runs fine on non SMP hardware..and before you ask...how do I know..I've had it installed before on single processor pc's.

Good enough?

nope, run any benchmarks? smp on non-smp is slower and really makes not much sense (suse is not a speed daemon anyway). running smp on non-smp is not really smart. problems with wireless, nvidia and a lot of other modules.


besides: default does not mean only smp.
One more idiotic move anyway (first was zen)

Looks like I started a lively conversation! I'll give the kernel package that broch mentioned a try...

for long time I have not run suse kernels.
Anyway:
make xconfig

Symmetric multi-processing support (SMP)

type: boolean
reverse dep: X86_NUMAQ && <choice>
prompt: Symmetric multi-processing support

defined at arch/i386/Kconfig:68

This enables support for systems with more than one CPU. If you have
a system with only one CPU, like most personal computers, say N. If
you have a system with more than one CPU, say Y.[/b]

From performance stand point running SMP on single CPU without HT will only slow down system. Even running HT on SMP (e.g. Intel Core Duo which does not support HT) or single CPU that does not support HT also slows down system and creates unnecessary overhead.

if default is already smp, then either try kernel-vanilla.i586.rpm or better build your own. Default kernel is quite heavy and un-optimized (as it has to fit as many possible hardware setups as possible). Not sure about reasoning behind setting smp as default. Maybe one reason is that on smp systems yast does not really know which kernel to install. If this is the case, then suse devs should work on better resolution than this pseudo fix.
