I upgraded my kernel to 2.6.19-gentoo-r6 this morning. I used genkernel. I followed these steps:Deleted the /usr/src/linux symlink and recreated it point to /usr/src/2.6.19-gentoo-r5 zcat /proc/config.gz > /usr/share/genkernel/x86/kernel-config-2.6 genkernel all After it successfully built, I opened up my /boot/grub/grub.conf file in vim and copied the entry lines for the old kernel I was using (2.6.18-gentoo-r6 - also created with genkernel) and changed the numbers to reflect the new kernel on the title, kernel, and initrd lines. However when I attempt to boot up with the new kernel, it goes through its usual device checks, and then right when it should say "Booting initramfs-{xxxx}", it says "/dev/sda6 is not a suitable root device." (or something like that) and offers me either a chance to enter the root device, or a shell. I asked for the shell. I did ls and saw a directory structure seemingly similar to my / on my root partition, but when I did ls /dev I didn't see any sda devices (or an other s* devices for that matter). What's gone wrong, and what do I do to fix it? Below is my /boot/grub/grub.conf:
I ran into a similar problem when upgrading. It looked to me like the SATA device configuration variables had been changed or renamed. This caused me to lose all my SATA modules when I rebuilt. After I went in and explicitly added the new SATA drivers into the config the machine could boot again.
Hope that helps. - Ben -- gentoo-user@gentoo.org mailing list
