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.

Cheers.
