Kernel problem when installing ubuntu 10.10

Asked by Alexandru Branzea

I just burned a dvd with a downloaded image(.iso) of ubuntu and installed it on 2 laptops with absolutely no problem. When i tried installing it on my computer, when linux loads from the dvd, (when that purple screen is visible) it suddenly crahses with the following message: "Kernel panic - not syncing: IO APIC + timer doesn't work! Boot with apic=debug and send a report then try booting with the 'noapic' option." Since i'm new to linux and dont know what that means, I tried using a usbstick but with the same kernel panic error.

Another detail would be that just above this message the installer shows the following lines:
...MP-BIOS bug: 8254 timer not connected to IO-APIC....
...trying to set up timer(irq0) through the 8259A....
...(found apic0 pin 0).....
....failed....

then it tryes to set up the timer as "Virtual Wire IRQ", fails and then it tryes to set up the timer as ExtINT IRQ which also fails.

At the moment i use winxp with absolutely no problem.

Hope that somebody can give me a hint or 2 on this problem. A nice day to evreybody!

Add the boot option:

noapic

To the kernel, should help

I added that boot option in the bootoptions (f6) and it worked, i was able to install ubuntu alongside windows xp. everything was alright untill i tried to boot from the newly installed ubuntu when the same kernel problem occurs. the linux grub menu is version 1.98(if it helps you). what command should i use to do exactly what "noapic" option did for me in the boot menu while installing?

Thanx in advance :)

you disabled the APIC (Advanced Programmable Interrupt Controller) as the one in your CPU is causing an issue with the kernel. You can add the option to the installed OS by holding shift at boot and pressing 'E' on the kernel and adding the option. Then press 'B' to continue to boot.

Once you get in the OS you can run:

gksudo gedit /etc/default/grub

change this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"

Then run:

sudo update-grub

The option will now stick and be applied to all future kernels too.

can you please be more specific? i'm new to whatever is related to ubuntu or to linux in general. when the sistem boots, i get to the screen where it prompts me to choose what os to choose. i can either choose an OS(ubuntu, ubuntu-recovery or winxp), run some memory tests, press 'e' to edit the commands before booting or press 'c' for a comand-line. I tried some of what you said, but i guess i did'nt wrote it where or how i should have done it.
hope im not getting on your nerves.

If you have same issue, apply same solution (F6...) and then apply actionparsnip solution.

I finnaly managed to discover how to do the trick. thx actionparsnip, you were a great help to me. I just had issues giving that command because i'm not familiarised with linux comand and how to issue them.
Thanx again and have a nice day.
