Guess that's one more thing to try with the dual core processors. you might just try running the 667Mhz ram at 533Mhz if there's jumpers or a bios setting. if this works, and htere are fine tuning settings for the ram, you might try the original 667 speed only add a clock to the CAS precharge (again, ift he BIOS has advanced manual memory timing options, some boards do, some don't) btw, have you tried running memtest86 on these systems ? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] CentOS 5.1 Core 2 Duo Install freezes
One more note, which explains why I posted on the CentOS list: I have no problems installing Fedora 8, or Ubuntu Gutsy 7.10 on these boxes. I haven't tried CentOS4.6, but that's not an option. I need CentOS 5.X. I've been using CentOS from the beginning of the project. I won't consider another distro in production systems. -Ken - Message from [EMAIL PROTECTED] - Date: Fri, 08 Feb 2008 18:56:58 -0500 From: Ken Price <[EMAIL PROTECTED]> Reply-To: CentOS mailing list Subject: [CentOS] CentOS 5.1 Core 2 Duo Install freezes To: CentOS mailing list Alrighty.

Always after verifying dependencies, and typically during the disk format process, the installation freezes. I get a "kernel panic - not syncing" in text mode. Single disks, dual disks, LVM, no-LVM, software RAID, even when disks are on a Promise SATA300-TX4. The single-core Celeron processors work fine, but none of the dual core processors work. I'm using 5 sets of hardware, so bad hardware is unlikely. I'm stumped. Anyone out there with similar problems and/or workarounds?

Have you tried any disk controllers other than the promise ? For me, if hardware SATA raid, it's 3Ware or nothing. I haven't ever really noticed good things said about other SATA raid cards. This is using the onboard SATA, or the promise SATA controller (not a RAID controller). Yeah, I've had problems capturing the entire panic. I'll try via a terminal on monday morning. I agree with the 3ware comment. My high-end MySQL and NFS boxes have 8-port 3Ware SATA RAID. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
