The first thing that jumps to my mind is you have an older initrd that has your HD drivers in it (such as ATA), but the newer kernel you've probably just built (is that what you mean by a bit of an update?) doesn't. Check for an initrd, and tell us what a bit of an update means :) You could also compare config files between your rescue CD and your system, if you can find it! HTH, -- Iain Buchanan iaindb at netspace dot net dot au Copy the live cd kernel to your machine and make it an option in grub and try booting that. Then at least you can stop chrooting and optical mounting. This will give us some information on if it is a kernel problem or not. Make sure to make modules_install If it's the kernel, check out kccmp to compare the kernel options between Live CD and the machine's kernel configuration after you dig up the configuration for the kernel on the Live CD. Other people are mentioning udev, and I wonder about this, too. Either before or after you check the kernel (whichever you decide is easier or seems better to you), can you chroot and rebuild udev through portage and also run a revdep-rebuild please? You said you updated, but it is not clear to me that the full update was proper. If you don't have revdep-rebuild, emerge the gentoolkit in the portage tree to get it, and check out the documentation to see what else it includes! ~daid

As your root-filesystem does appear to be mounted, can you give use the result of the mount command to see how it identifies the root-filesystem? I have seen harddrive naming schemes change between kernel versions. Eg. hda might end up being hdb or hdc,... (same with sd.) Alternatively, to avoid this, you could use drive-labels and configure /etc/fstab with these labels rather then the drive-items. Can you also show us the dmesg-output to see if the drives are actually identified? If udev is not running correctly, the device-nodes might not be created automatically. -- Joost
