 |
|
Hi, I am in some trouble. After I gave up on Fedora15, I decided to install gentoo. I followed the installation guide x86 (I have a quite old machine AMD athlon Xp 1600+ 768 mb ram +nvidia geforce fx 5200+hdd ide 80gb), after I installed/configured grub, I reboot and get this:

I don't know what to do ... it seems a problem with the ext4 and the kernel config but not sure.

Hi, jvmnck. Welcome to Gentoo!
This problem typically indicates that support for the type of the root filesystem was not built in to the kernel. The error also indicates that you most likely configured your own kernel instead of taking the genkernel route, right?
In any case, this is easily correctable:- Boot the install media, whatever that was.
- Re-mount all of the partitions and re-enter the chrooted environment. If you need help, see NeddySeagoons' Rough Guide to Chrooting. Just to be sure, run "mount" and confirm that the /dev/sda8 partition is indeed ext4. If not, report back here.
- Change to the kernel source directory and rerun "make menuconfig", just as decribed in the Handbook.
- Add the driver for your filesystem (ext4). You'll find it at
| Code: | -> File systems
-> The Extended 4 (ext4) filesystem |
Make sure to make it built-in <*> as opposed to built as a module <M>.
Per the Handbook, rebuild the kernel and copy the kernel image to /boot.
Per the Handbook, exit the chroot, unmount all filesystems, and reboot.That should do it. Report back if you have any issues. 
- John

Hhm, of course, the file system driver needs to be compiled into the kernel or should be available via an initrd early enough - but :
From the screen shot it seems, that grub looks for /boot at /dev/sda8, but /boot (=="root" in grubs naming schema) is /dev/sda3. Therefore setup grup again, eg. | Code: | setup (hd0)
root(hd0,2) |
or something similar.

jvmnck,
Welcome to Gentoo.
In your image, the line that says | Code: | | Could not find root block device in . |
Should contain a list of all of the block devices the kernel can see. In your case, none.
From your very brief (for a Genkernel kerenl) list of modules, I suspect you have used genkernel then turned off all the things you thought you didn't need.
Your kernel needs the following | Code: | | [*] PC BIOS (MSDOS partition tables) |
support
That allows the kernel to read your partition tables.
| Code: | | < > ATA/ATAPI/MFM/RLL support (DEPRECATED) ---> |
must be off. Here be dragons.
| Code: | <*> SCSI disk support
<*> SCSI CDROM support
<*> SCSI generic support
[*] Probe all LUNs on each SCSI device |
You only actually need SCSI disk support to boot but you will wamt the other items later.
Your hard drive interface | Code: | | 00:14.1 IDE interface: VIA Technologies, Inc. VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06) |
uses the PATA drivers under the | Code: | | <*> Serial ATA and Parallel ATA drivers ---> |
choose
| Code: | [*] ATA SFF support
[*] ATA BMDMA support
<*> VIA PATA support |
For ext4 you need | Code: | | <*> The Extended 4 (ext4) filesystem |
That should get you started.

Well first thanks to everybody, John R. Graham, toralf and NeddySeagoon.
"The error also indicates that you most likely configured your own kernel instead of taking the genkernel route, right? "
| Code: | | [*] PC BIOS (MSDOS partition tables) it was already |
| Code: | | < > ATA/ATAPI/MFM/RLL support (DEPRECATED) ---> ____it was already |
| Code: | <*> SCSI disk support ____it was already
<*> SCSI CDROM support ____it was already
<*> SCSI generic support ____it was already
[*] Probe all LUNs on each SCSI device ____it wasn't |
| Code: |
[*] ATA SFF support ____it was already
[*] ATA BMDMA support ____it was already
<*> VIA PATA support ____it wasn't
|
| Code: | | <*> The Extended 4 (ext4) filesystem ____it was already |
After I added the two missing (and removing many like selinux, hybernate and many drivers sata ethernet, processor multi core), and rebuilding, I restart. And ...
Yes, it boot!!!!  thanks NeddySeagoon
I still have many minor issues like: no iwconfig, no framebuffer, wrong keymaps (the boot sequence throws 2 errors !! one is the keymaps and the other I can't read it because the output goes to fast). Anyway that's another thread, so again thanks |

jvmnck,
| Code: | | <*> VIA PATA support ____it wasn't |
Was the killer.
All those other things you have missing are because you have not installed them.
Gentoo gives you two things:-
The packasges you ask for and the packages you must have to support the packages you ask for.
