Jeff, I simply wanted to add that I agree with John's concern over the Dell Optiplex 280 hardware support in Enterprise Linux 3. If you are not aware, Dell has completely discontinued shippment of the 270-series. This is a shame in some ways, since it ran Enterprise Linux 3 beatifully. This means that those in our market are forced to find an alternative for inexpensive desktops with the fast FSB we come to love; the 280-series is the likely candidate. Please let us know if we can be any help with test kernels and etc. We have a single SX280 on the bench for exactly that purpose. Cheers. Note that current RHEL3 and RHEL4 support up to 4 SATA ports on ICH6 just fine, using the ata_piix drivers. AHCI is only required if you need support for more than 4 ports, or if you want additional performance and NCQ support. AHCI is not _required_ for operation. We are seeing problems with booting Dell Optiplex 280's with Red Hat Enterprise 3 U3 (2.4.21-20.EL). If the BIOS is in SATA compatible mode, the 2.4.21-9.ELsmp kernel will boot without problems. If the 2.4.21-20 is used it fails in a fairlycant fidn the hard-drvie way VFS: Cannot open root device "LABEL=/" on 00:00 Please append a correct "root=" boot option Kernel panic: VFS: Unable to mount root fs on 00:00 Am wondering if an extra section to /etc/modules.conf needs to be added to get the ati_piix module installed (and if kudzu did not install it). We are also checking to see if any Dell BIOS updates are needed. We have just taken delivery of a system based on the intel D915GAVL motherboard. This moboard uses the 915G chipset. It exhibits the problems listed in this bug report when we try to boot with the 2.4.21-20 kernels but is fine with previous RHEL 3 kernels. When displaying the hardware list on boot it lists the DVD drive on the PATA controller and then says "ide0: ports already in use, skipping probe" instead of listing hda and hdb. It then goes on to the reported problem finding the kernel (because it can't find the drive). The BIOS in this motherboard doesn't do PATA emulation for SATA drives so we're dead in the water until this problem is resolved. Is there a work-around that can be passed in the grub boot or put in /etc/modules.conf? For those playing along at home who are looking for a workaround, the trick is to boot an old (working) kernel, make sure you have alias scsi_hostadapter ata_piix in /etc/modules.conf (it was already there for me) cd /boot preserve the initrd files that you care about just in case mkinitrd initrd-2.4.21-20.0.1.EL.img 2.4.21-20.0.1.EL.img then edit /etc/fstab and /etc/grub.conf to look for /dev/sd instead of /dev/hd. I had to change the BIOS setting for the SATA controller to "legacy" to get the older kernels to boot. This doesn't fix the NIC not having a driver at all but it does make the system bootable. A fix for this problem was committed to the RHEL3 U5 patch pool on 14-Feb-2005 (in kernel version 2.4.21-27.13.EL). An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
