 Posted: Thu Jul 27, 2006 10:33 pm Post subject: kernal panic |
 |
|
I have reinstalled from scratch twice and i know i followed the instructions to the point. but now i get a kernal panic at boot up.
it is saying
VFS: cannot open root device "hda3" or unknown-block (0,0)
please append a correct "root"=boot option
Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)
When i edited the grub i put
default 0
timeout 10
title=Gentoo
root (hd0,0)
kernel /boot/kernel root=/dev/sda3
What is going wrong

Hi.
Post the output of lspci and the contents of your grub.conf or lilo.conf file.
The VFS: cannot open root device "hda3" or unknown-block (0,0) error message means that you didn't build the support for your storage controller in your kernel <*> and not as a module <M>.

I ran into the same trouble with linux-2.6.17-gentoo-r4,
my grub configuration is below:
| Code: | default 0
timeout 5
title Gentoo Linux 2.6.17-gentoo-r4
root(hd0,7)
kernel (hd0,7)/bzImage-2.6.17-gentoo-r4 root=/dev/hda10
title Gentoo Linux 2.6.16-gentoo-r13
root(hd0,7)
kernel (hd0,7)/bzImage-2.6.16-gentoo-r13 root=/dev/hda10
title=Window XP
rootnoverify (hd0,0)
makeative
chainloader +1 |
this configuration is work with 2.6.16 kernel on my IDE hard disk,
but kernel 2.6.17v fall into panic.
my root file system is ext3, and I believe that I have compiled build in support it. |

robinswan,
post the output of lspci. Check if you have ext3 compiled in with
| Code: | | # grep -i ext3 /usr/src/linux/.config |
