 Posted: Fri Aug 18, 2006 8:32 pm Post subject: Another Kernel Panic. (Solved) [Human Error] |
 |
|
I'm sorry, I don't want to waste your time, but I couldn't find out this problem in the forums.
You have read it thousand times, but it is really annoying that a kernel chrashes booting with a normal HD, non-sata, non scsi, non-firewire...
The error
| Code: | UFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing : UFS: unable to mount root fs on unknown-block(0,0)
<?>uhci_hcd 0000:00:07.2 suspend_rh (auto-stop) |
My grub.conf
| Code: | default 0
timeout 5
splashimage=(hd0,0)/grub/mammatus.xpm.gz
title=Gentoo Linux 2.6.17-gentoo-r4
root (hd0,0)
kernel /boot/linux-2.6.17-gentoo-r4 root=/dev/hda3 |
My fstab
| Code: | /dev/hda1 /boot ext2 defaults,noatime 0 0
/dev/hda3 / ext3 noatime 0 1
/dev/hda2 none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom auto noauto,ro,user 0 0
/dev/hda4 /backup fat32 rw 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs nodev,nosuid,noexec 0 0 |
What did I miss?
Sorry, I'm a really n00b at this, but I wanted to know "How is it inside", and needed to run a light kernel on my server, a PIII 500MHz, xD So as to not use Ubunto and similars...

Change the kernel line in your grub.conf to | Code: | | kernel (hd0,0)/boot/linux-2.6.17-gentoo-r4 root=/dev/hda3 |

Nope, it didn't work... The same kernel panic.
I have tried variations such:
| Code: | root (hd0,2)
kernel (hd0,0)/linux-2.6.17-gentoo-r4 root=/dev/hda3 |
Or:
| Code: | root (hd0,2)
kernel (hd0,0)/linux-2.6.17-gentoo-r4 root=(hd0,2)/dev/hda3 |
But it doesn't work...
If it helps... My hd(0,2) or /dev/hda3 is a ext3 partition and my boot partition is ext2
I loads the kernel, if I change a lot the line "kernel" a message turns up saying "no kernel" 
Perhaps I made a mistake building the modules to read ext3 (i think I didn't) or should I choose another kernel version? |

| Make sure to build-in the appropriate IDE drivers and ext3 (build-in, not as a module). |

I have just done it.
I included and built lots of unnecesary modules (generic modules, etc.)
I have checked all the ext3 modules and IDE,DMA,etc.
(In one of the choices of building, "make" suddleny stopped)
The same kernel panic appeared.
Any idea?
P.D. I'm trying with another kernel version, I think I will use 2.4...  |

You do usually
cp arch/i386/boot/bzImage [preferred kernel location here]
after you´re done making don´t you (otherwise it wouldn´t make any sense, since you´re not updating your kernel) ?
And you don´t have to built-in all sorts of crappy modules you probably won´t use anyway.
Just make sure you got the Generic IDE-modules compiled in. |

Well, the kernel is loaded anyway...
The problem, my problem, is that the kernel can't open the /dev/hdq3 partition (or whichever partition you set as root)
I tried building the same kernel with genkernel, but it wasn't successfull, it loaded, it printed a lot of yellow errors, but ir loaded and runned.
The next step i'm going to do is to try rebuilding another kernel manually, vanilla sources will be the better choice...
I'm sorry, I compiled the kernel (and the modules inside) 4 times and I got gcc crashes and kernel panics, but i did choose the IDE modules to be built in.
I'm not going to resolve this mistery, I'm avoiding it... I need my server ready for yesterday.
If I am succesfull building another kernel with the same options I will tell you the sooner I can .
P.D.Thanks Anyway, Thanks for your time  |

I tried once again and I got the same error...
What should I do?
Is there anything wrong in the handbook?
Could it be an error of udev?
Must I have an initrd image or something of kind?
(I read in the kernel documentation that I mustn't build the ext3 as a module if im going to use this filesystem as "/"..., is it true?)
I'm hopeles... I tried genkernel and was succesfull, but it loaded too much, and was all x86 generic binaries...
Please, a bit of help, do you need any of my archives to be printed here? |

Assuming you know how to configure your kernel properly, you can use genkernel with the --menuconfig flag: In terms of configuration this is no different to doing it 'manually', but genkernel will remember the kernel build steps for you. |

My excuses, you can now call me 'n00b'...
I explain: I was building modules inside the kernel, and main fuctions as modules...
Yes, that's why I'll alwais be a noob.
A simple mistake of understanding...
I still not-knowing how could the kernel load without the correct modules built-in, but it is solved.
Human constant, human error, sorry |
