kernel panic/unable to mount root on ...

[f41t3r]

1st boot after installation:

Code: Select all

VFS: Cannot open root device "303" or 03:03
Please append correct "root=" boot option
Kernel panic: Unable to mount root fs on 03:03

lilo.conf:

Code: Select all

boot=/dev/hda
prompt
timeout=50
default=gentoo
vga=771
image=/boot/kernel-2.4.28-gentoo-r5
label=gentoo
root=/dev/hda3
other=/dev/hda1
label=windoza

my hdd:

Code: Select all

/dev/hda1 vfat - winda
/dev/hda2 ext2 active - /boot
/dev/hda3 ext3 - gentoo
/dev/hda4 - swap

I didn't use genkernel. Any body can help ?

I had a similar issue with grub and a 120gb drive. I added "hda=remap" to the boot options and that made it work.

I had to add that because western digital installed software on the drive in the same area that the bootloader is installed and it caused things to break.

[f41t3r]

ok, now i have

Code: Select all

boot=/dev/hda
prompt
timeout=50
default=gentoo
vga=771
image=/boot/kernel-2.4.28-gentoo-r5
label=gentoo
root=/dev/hda3
append="hda=remap"
other=/dev/hda1
label=windoza

and unfortunately it still isn't working - the same error message
p.s. yup i have wd too

Be sure to statically include the root fs and your hd controller drivers in the kernel.

bye,

[f41t3r]

i think 2 it's realated with some kernel options, but i must avow i don't know really where to search it ...

[f41t3r]

few minutes ago i had recompile the kernel

for now there is only one line of error: Kernel Panic: Unable to mount root on 03:03

these are some parts from .config file maybe it will help you to find the bug , thx anyway.

Please report also your root filesystem and your hd controller chipset

[f41t3r]

root fs is ext3; hd controller chipset ? where can i find information about it ?

[active]

I think on the installation manual of your motherboard, or on Google, by typing the name/model of it.

[f41t3r]

ok, i've found this information about chipset in the motherboard manual:

Chipset:

VIA KT400 North bridge
ViA VT8235 South Bridge
-Dual channel Ultra DMA 33/66/100/133 master mode EIDE controller

[active]

So, it seems that you have all the needed support included. So the only solution that comes to my mind is to add the option "read-only" to the linux section

Try to see here
http://www.netadmintools.com/html/5lilo.conf.man.html
if there are information useful to you..

[rouben]

I am having the same issue, except with reiserfs, and my IDE chipset is nVidia nForce. I am trying this out on a Compaq Presario R3310 laptop (maybe you know of some quirks with that model ).

The funny thing is that a 2.4 kernel with an identical configuration boots fine. It's just the 2.6. kernels that I am having problems with...

After Googling for a while I noticed that a lot of people have had this issue on a variety of distributions, from Fedora to Debian. So far the only two solutions I've seen were:

• Make sure the IDE chipset and filesystem support is compiled in
• Use an initrd image and let it do the mounting of the root fs

I have tried both, many times, under different conditions... I'll watch this thread with hopes that something interesting will come up.

Thanks in advance!

rouben: try to post here your boot loader config file. If you use "LiLo", have you tried to use Grub? If yes, did you find the same problems? (this is useful also for f41t3r)

rouben: try to post here your boot loader config file. If you use "LiLo", have you tried to use Grub? If yes, did you find the same problems? (this is useful also for f41t3r)

I'm using Grub, I stopped using LILO a while ago.

My grub.conf is pretty simple:

Code: Select all

title Gentoo 2.6
kernel (hd0,4)/boot/kernel-2.6 root=/dev/hda5

title Gentoo 2.4
kernel (hd0,4)/boot/kernel-2.4 root=/dev/hda5

I didn't use genkernel, and I'm positive that I have both my IDE chipset and filesystem drivers built into the kernel (I doublecked this ad nauseum, I even built a kernel will all the IDE and filesystem options built-in, not as modules, but to no avail). After all, 2.4 kernels with identical configs are able to boot just fine using identical lilo configs.

At first I thought this is related to the fact that I have a single partition for everything (i.e. no separate /boot partition), or perhaps because I used reiserfs rather than ext2 or ext3. However, after researching this a bit, I noticed quite a few people having exactly the same issue with ext2, ext3 and reiser...

Actually, just now, I notices something interesting that has a direct connection to my (and perhaps everyone else's) problem. The following line in my kernel output, just after the IDE chipset lines, right after the hda geometry output:

/dev/ide/host0/bus0/target0/lun0: unknown partition table

That would definitely explain the error I've been getting, now wouldn't it? I never noticed this line before, in part because I never tried to boot the kernel in a high-res framebuffer mode and this line zipped by too fast for me to see. I am curious, f41t3r, do you notice anything similar to this in your kernel output, when you try to boot?

I'm using the latest 2.6 gentoo-dev-sources, by the way. I've tried some older releases too.

[active]

rouben it's quite strange.
First of all try to add to:

Code: Select all

title Gentoo 2.6
kernel (hd0,4)/boot/kernel-2.6 root=/dev/hda5

this:

Code: Select all

title Gentoo 2.6
root (hd0,4)
kernel (hd0,4)/boot/kernel-2.6 root=/dev/hda5 

If the error persists, it could be:
1) an IDE + devfs problem
2) an ugly conversion from 2.4 to 2.6 kernel branches
In this case it could be useful also to emerge the linux26-headers, and try recompiling devfs. I think you should find out a guide on how to migrate from 2.4 to 2.6 on gentoo related docs.

[rouben]

Thanks for the tip. Actually, I think my partition table is hosed. First of all, the computer was pre-installed with Windows XP Home (and I heard some rumours of weird partitioning artifacts on such systems). Secondly, I used PartitionMagic 8 to do a non-destructive resize in order to allocate some space for Gentoo, and ever since I kept getting odd behaviour out of both GRUB and the NTLDR (Windows' boot loader). When I examined the partition table in fdisk, I got an error message saying that the MBR and at least one of the boot records was invalid... anyway, what I am trying to say is that probably PartitionMagic did something nasty.

I'm using QTPartEd/PartEd next time.
