 |
|
Hi Gentoo folk - I am trying to install Gentoo and am having a few problems with bootup.
Boot fails with the message:-
| Quote: | VFS: Cannot open root device "SDA10" or unknown block (0,0)
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown -block(0,0) |
Yeah - I know.. I have been reading the Grub Error Collection.
I have checked the the kernel does support the ext3 flesystem.
I have selected <*> Include IDE/ATA-2 DISK support I have a 160G SATA hard drive.
I have checked that the "boot" symlink in /boot points to /boot. (Repeatedly clicking on the "+" in the Konqueror filemanager tree display makes it do /boot/boot/boot/<files >  )
The interesting thing is MEPIS and SuSE 10 boot OK without problems from the very same grub.conf.
The boot partition is on /dev/sda1 The Gentoo partition is on /dev/sda10
My grub.conf looks like this:-
| Code: | # Modified 25/6/2006 GENTOO /boot/grub/grub.conf
# This used to be the MEPIS installation boot on sda9.
# It also boots OPEN SuSE SUPER-1
# It once used the name "menu.lst" instead of "grub.conf
# Now, this file is used by GENTOO, as the master grub bootloader.
default 0
timeout 20
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
# Copied from the MEPIS "menu.lst"
title MEPIS at sda9, kernel 2.6.13-15.ck6.SUPER.1-i386tsc

Surely this is just some stupid fumble - but I can't see it yet. I admit I don't know much about modules (yet), but at this stage, I didn't mess with them. I had the kernel compile the options I saw as obvious (processor type, etc.), and I kept the USE variable down to a few very simple choices.
I am still trying stuff suggested in the Grub Error Collection sticky, but would appreciate any help.
Thanks |

What is the exact output of
Are you sure you are editing the right file? Seems odd to me that the error message show SDA, but the fstab entry is sda. (should be sda)
This | Code: | | kernel /kernel-2.6.16-gentoo-r7 root=/dev/sda10 vga=0x317 |
should be the proper line when using a separate boot partition for Gentoo.
What filesystem is /dev/sda10? Is the support for it compiled INTO the kernel? You're not using a initrd ramdisk, so it can't be compiled as a module. |

You need to select the correct chipset driver for your SATA controller (look at the output of lspci).
You can find this driver in the SCSI section (not the IDE section). |
