RE: [suse-amd64] Quad opteron performance issues in suse 9
Yep, I gave kernel-smp-26-2.6.1-5.x86_64.rpm a try and got a kernel mode panic, something about the file system. I'm using an lsi logic 320-2 megaraid controller, suse is installed on a resier file system on an array off the lsi logic.

Are there any 2.6 kernels available for suse 9, pre-built? Haven't had a whole lot of luck building one.
Yes, there are - in ftp.suse.com/pub/people/kraxel Andreas

I've been playing around with Suse 9 AMD64 for the past few days, trying some canned benchmarks and one that we've constructed.

The kernel is fine for 4 ways and it scales with our experiments.
The 2.6 kernel is far less locks than 2.4 so depending on your tests, updating might make a difference.
A side issue, for some reason you cannot install the rpm binaries of

4.0.17 without getting a segmentation fault. So all of the mysql testing
Please tell that to those that did the rpms...

megaraid controller, suse is installed on a resier file system on an array off the lsi logic.
And that lsi logic is loaded correctly? Andreas

If you mean this readme: ftp://ftp.suse.com/pub/people/kraxel/README No, I just rpm installed the kernel and rebooted. Excuse the lack of experience, some questions: 1. Where does one find these updated rpms? I found mkinitrd-1.0-110.x86_64.rpm, but can't find aaa_base or modutils. 2. after those modules are installed is it just rpm -Uvh kernel.rpm? When I ran it the first time it updated the bootloader itself. Again excuse the basic questions, but this is a first for me.

AFAIK those are not needed, they are already working in 9.0.
2. after those modules are installed is it just rpm -Uvh kernel.rpm?
Yes.
When I ran it the first time it updated the bootloader itself. Again excuse the basic questions, but this is a first for me.
