It seems I got a reply(?) to my previous post. His follow contained nothing informative, but seems to be misleading, so I decided to add my comments. My previous post refered to rather kernel version and BIOS. This is why I plan to test opensuse 11.0 Alpha1. FC8 seems to have newer kernel than opensuse10.3. The trouble of Phenom I mentioned occurs in my place even if it runs with the default clock. I did not say troubles started with OC. Troubles exist without OC. Meanwhile, in my lab, several Intel's quad6600s are running at 3.0GHz, forming reliable clusters with opensuse 10.2. yoriaki fujimori -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
