 Posted: Fri Jul 31, 2015 7:26 am Post subject: Kernel panic - not syncing: No working init found [SOLVED] |
 |
|
New installation on a Samsung NC10 (Intel Atom processor). Manual kernel build.
A photograph of the error is here: https://drive.google.com/file/d/0B0JkugWV87y8U3g5OE9ZbkRGckU/view?usp=sharing
https://www.kernel.org/doc/Documentation/init.txt gives an architecture mismatch as a possible cause.
This is the stage3 file I used: stage3-i686-20150721.tar.bz2, which I think is correct for the Intel Atom processor.
Suggestions as to where to look next, please.

did you use gentoo-sources and enabled those gentoo specific / udev specific kernel settings?
you may use a genkernel kernel first and adapt it. or a kernel seed.
and did you specify root and other stuff for the kernel in the kernel line of your bootloader? I had similar errors after recovering from "ubuntu" deleting" my grub.config and the root cause was missing kernel flags after recovery.
you may need an initramfs too.
check filesystem support / hardware support too. |

| There must be something missing in your kernel configuration. Can you pastebin it? |

Yes

I used Grub2, so it did all that for me. This is the relevant section from grub.cfg:
| Code: | menuentry 'Gentoo GNU/Linux' --class gentoo --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-52131baf-0e78-418b-9c56-e6a30dc6f59d' {
load_video
insmod gzio
insmod part_msdos
insmod ext2
set root='hd0,msdos1'
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1 438b939e-9f37-48f4-9c6b-8c8afa6
36482
else
search --no-floppy --fs-uuid --set=root 438b939e-9f37-48f4-9c6b-8c8afa636482
fi
echo 'Loading Linux 4.0.5-gentoo ...'
linux /vmlinuz-4.0.5-gentoo root=/dev/sda3 ro
}
|
This is my fstab:
| Code: | /dev/sda1 /boot ext2 noauto,noatime 1 2
/dev/sda3 / ext4 noatime 0 1
/dev/sda2 none swap sw 0 0
|
| Quote: | | check filesystem support / hardware support too. |
Yes, both ext2 and ext4 enabled.
Thanks for the suggestions. |
