 Posted: Sat Oct 18, 2003 8:23 pm Post subject: Kernel panic: No init found |
 |
|
A happy Gentoo-user I was. One by one my reiserfs partitions were starting to bail out on me. No other option than a reinstall with ext3 filesystems.
Being a linux user since kernel 2.2.5 I thought a reinstall to be a breeze. But after 2 days of trying to get my kernel to boot I ran out of options.
This is the last part of my bootscreen:
| Code: |
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
mount_devfs_fs(): unable to mount devfs, err: -2
Freeing unused kernel memory: 120k freed
Warning: unable to open an initial console.
Kernel panic: No init found. Try passing init= option to kernel |
I have searched the gentoo-forums for two days, but I can't find the answer to this problem.
My disks are ordered like this:
/dev/hda6 boot
/dev/hda7 swap
/dev/hda8 root
My fstab:
| Code: |
/dev/hda6 /boot ext2 noauto,noatime 1 2
/dev/hda8 / ext3 noatime 0 1
/dev/hda7 none swap sw 0 0
# NOTE: The next line is critical for boot!
none /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink). Adding the following
# line to /etc/fstab should take care of this:
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will use almost no
# memory if not populated with files)
none /dev/shm tmpfs defaults 0 0
|
My lilo.conf:
| Code: | menu-scheme=Wb
boot = /dev/hda
prompt
map = /boot/System.map
lba32
timeout=30
delay = 50
default=Gentoo
vga = normal # Normal VGA console
# End LILO global section
# Linux bootable partition config begins
image = /boot/vmlinuz-gentoo-2.4.20-r7
root = /dev/hda6
label = Gentoo
read-only # read-only for checking
append="hdc=ide-scsi"
# Linux bootable partition config ends |
My kernel-config was taken from the previous install. I only pulled out the framebuffer things to make things easier on first boot.
Does anyone have a tip where to look? I getting pretty desperate. |

I think ext3 is not the culprit. It says "EXT3-fs: mounted filesystem with ordered data mode."
But devfs is bugging out (I think). Look at the kernel config, devfs needs to be automatically mounted AFAIK.
I've seen similar problems on a P4 system with raid, I'm still not sure why the kernel crashes like that.
hth,

| To me this sounds like you did not enable devfs to be mounted on boot, gentoo needs that to work. |

If you mean the part in the kernel about devfs, I already enabled that. There are two items about devfs:
[*] /dev file system support (EXPERIMENTAL)
[*] Automatically mount at boot
I have enabled them both.

I have a raid volume in my system also. However this volume is not part of any system volume. Could it be somehow involved? If I look at the kernelmessages it's getting detected ok. |

I'm not a lilo user, but I think root = /dev/hda6 must be root = /dev/hda8 in your lilo.conf. root=/dev/hda8 will be passed to your kernel and your kernel will use this as it's root.
Good luck,
Frank

Aaaarghhh, I feel like a complete idiot. This is the typo I missed. Of course the devfs can't be mounted, there is no /dev in the boot volume. 
I'm going to hide under my bed until the voices in my head screaming "idiot" go away.
Many thanks, this solved it.  |

i'm having the same problem. i have the adutmount at boot enabled and devfs enabled but it stil gives me the kernel panic. my lilo.conf looks good and i'm not sure about my fstab..i'll show it
/dev/hda3 /boot ext3 noauto,noatime 1 1
/dev/hda4 /boot ext3 noatime 0 0
/dev/hda5 none swap sw 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
and if you want my lilo.conf i can give it to ya too.

The problem I havce had is similar to yours. The best way to figure the problem out is to get your hands dirty...*reinstall*. Ensure you don't have any typos and mount each file system after you have reread the coding. Other than that keep searching the forums.It's in here..(the answer).

Are you really trying to mount two different partitions onto /boot  ? I'd make sure that one of these lines has / as the mount point rather than /boot. If that's a typo here and not in your fstab, then check that whatever is mounted at / is also being passed to the kernel as root= in your lilo.conf
Hope that helps...

cool thanx. i just ran:
emerge -C gentoo-sources
and i'm compiliing my kernel as i type lol. (using a mac computer at work)
and i'm just going to copy is and see what happens from there. also that line about 2 devices on /boot. (its a typo in the post, great way to get help eh? ) it should read:
/dev/hda4 /boot
/dev/hda3 /
just for clearing up purposes. but i would like to point out that i've mounted dev/hda4 as boot but i dont want it mounted as boot, but mounted as /mnt/home so do i just:
umount /mnt/gentoo/boot
then,
mkdir /mnt/home
mount /dev/hda4 /mnt/gentoo/home
would that take care of it?

If you don't mind telling; what mobo are you using? Also, name the intergrated or non-intergrated componets; processor,eth card,etc.
