View Full Version : [ubuntu] Start up error after upgrading to 8.10

Hello everyone! I was upgrading to Ubuntu 8.10 from 8.04. I did something wrong:I left the computer unattended for a few hours. When I came back, the screen was blank. I know all the components had downloaded and the installation was in progress when I left.

I am getting the following error right after boot up:

Starting up...
[ 0.000000] ACPI: BIOS age (1999) fails cutoff (2000), acpi=force is required to enable ACPI
[ 0.884544] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Does anyone know what this could be? I was ready to re-install using the Kubuntu CD as I recently wiped out Windows out of my wife's laptop and is now running Kubuntu perfectly fine. My laptop is an old IBM Thinkpad, 600X with a Pentium III 600 MHZ, 512 Ram, and a 10 gig hard drive. Ubuntu 8.04 was running perfectly fine, flawlessly. I was also thinking about a minimal installation. Thanks in advance for any help you could provide.

Can you boot with the old kernel from 8.04? Then, post your /boot/grub/menu.lst (without the lines that have # in front since those lines are comment) here.

Applications -> Accessories -> Terminal

sudo cat /boot/grub/menu.lst

Actually, I can not fully boot into anything. I get the error message right after it says that grub is starting. I can not boot into 8.04 or 8.10.

I wonder if I had to tweak the bios because of the error code? Also, if I start my laptop using the Kubuntu 8.10 live cd, can I extract information from the laptop that can tell me what the problem might be? If I need the Ubuntu live cd, I can download it as well.

If you can boot your machine from a LiveCD, then you can mount the partition where /boot is located, and look at /boot/grub/menu.lst to see if there is any typo in it, preventing the system to boot.

Assuming that the partition where /boot is located is /dev/sda1, do something like these from the LiveCD.

Applications -> Accessories -> Terminal

sudo mkdir /mnt/ubuntu
sudo mount -t ext3 /dev/sda1 /mnt/ubuntu
sudo cat /mnt/ubuntu/boot/grub/menu.lst

Ok, this is what I get when following this

sudo mkdir /mnt/ubuntu
sudo mount -t ext3 /dev/sda1 /mnt/ubuntu
sudo cat /mnt/ubuntu/boot/grub/men

Is there anything I should change/edit? I get the following:

Interesting that you don't have a "initrd" for 2.6.27-7-generic kernel. Edit /mnt/ubuntu/boot/grub/menu.lst


gksudo gedit /mnt/ubuntu/boot/grub/menu.lst
and add this line


initrd /boot/initrd.img2.6.27-7-generic
after the kernel entry and before the quiet. It should look something like this for the first title.

Save it and reboot. Now, see if you can boot Ubuntu from your harddrive.

Unfortunately, I am still having problems. After reading many posts here, it seems that 8.10 had some bugs. As for me, it seems that the problems are cause by kernel 2.6.27-7-generic somehow, although I lack the skills to properly determine this. However, my Kubuntu laptop started having problems after a kernel update to this version as well! The problems are similar to the ones on my Ubuntu laptop.

The funny thing is that I can start the laptop only using the 2.6.24-21-generic (recovery mode) kernel. I can only start the system using XFCE and not Gnome and I get an error message that HAL can not start? I can not connect to the internet, which limits my options of updating and upgrading the system. So, the saga continues for me. I am thinking about installing 8.04 back in the system as that was working flawlessly for me.
