|
|
I installed gentoo 1.4 with gaming sources (custom kernel), grub.
When I reboot I get the following error message:
ds: no socket driver
bad magic number
sb validate failed
Kernel Panic : VFS: Unable to mount root fs on 03:04
/etc/fstab
/dev/hda1 windows
/dev/hda2 /boot
/dev/hda3 /swap
/dev/hda4 /
Any help will be welcome. I will not attempt to reinstall (too much work). I will wait for help from the community here. Thanks in advance. _________________ "Persons attempting to find a motive in this narrative will be prosecuted; persons attempting to find a moral in it will be banished; persons attempting to find a plot in it will be shot."

If that is the content of your fstab, then there is little wonder why the root file system could not be mounted. You should check out the man page for fstab. You'd be better off basing your fstab off the one provided by gentoo, adjusting as necessary. |

Ozukir@ is right about that one, use the gentoo /etc/fstab from the installation and edit it to your needs, making one like that will definitly not work.
Also, show your grub.conf file, that could provide clues. |

Here's a sample for you which may match your config, but you'll have to get the filesystem types correct:
Code: | /dev/hda1 /mnt/winC vfat uid=1000,gid=100 0 1
/dev/hda2 /boot ext2 noauto,noatime 1 2
/dev/hda3 none swap sw 0 0
/dev/hda4 / reiserfs noatime 0 1 |
Of course you would have to make sure the filesystem type is correct for your partitions! If you use a reiserfs for /boot you'll also need a notail option.
The first line (of course) would be optional--you may not want to have your Windows partition available to Gentoo. If you did, though, you would need to create a directory for mounting your windows partition at /mnt/winC:
This is just a sample. Don't copy it straight over and assume it will work for you. If you post more information on your filesystem choices we could post a configuration that would probably work for you. _________________ Kent

2 am.
Here's a deprecated version of fstab
/dev/hda2 /boot ext3
/dev/hda4 / reiserfs
/dev/hda3 none swap
/dev/hda1 /windows ntfs
grub
default 0
timeout 30
Splashimage=(hd0,1)/boot/grub/splash.xpm.gz
titlle=Gentoo Linux
root (hd0,1)
kernel (hd0,1)/boot/bzImage root=/dev/hda4
title=Windows xp
root (hd0,0)
chainloader (hd0,0)+1 _________________ "Persons attempting to find a motive in this narrative will be prosecuted; persons attempting to find a moral in it will be banished; persons attempting to find a plot in it will be shot." Mark Twain. |

Ok, then try:
Code: | /dev/hda1 /mnt/winC ntfs uid=1000,gid=100,ro 0 1
/dev/hda2 /boot ext3 noauto,noatime 1 2
/dev/hda3 none swap sw 0 0
/dev/hda4 / reiserfs noatime 0 1 |
Unless you're running a 2.6 series kernel you'll only have read-only access to the ntfs partition, and you'll have to make sure the ntfs support is included in the kernel. _________________ Kent

I hate to be the one giving more help than necessary, especially when sufficient help has already been delivered. But if you're gonna hand hold all the way to a complete fstab I must point out that you're missing Code: | none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0 | You might as well include the floppy and cdrom (assuming that you have those). While they're not necessary to boot the system, I'm sure you'll eventually find them useful. Code: | /dev/fd0 /mnt/floppy auto noauto,user 0 0
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,user,ro 0 0 |

One you might miss and it's a easy to make error if you are tired is assuming the 1 down numbering scheme of grub extends to the root statement.
"kernel (hd0,0)/boot/bzImage root=/dev/hda3"
" /dev/hda3" is really "/dev/hda3" not "/dev/hda2".
You get a kernel panic error message of unable to mount root drive doing that one to. ( ahem I did that when I got up at 3 am to check on progress and decided to go for it , but one huh? at the error message and I stuck the installation disk back in and re-edited grub.conf )
But I will say grubs nice now that I've gotten used to it. |
