kernel panic - not syncing : IO-APIC

marvelade · 04-08-2007, 03:47 PM

Hi All,

When I boot Linux I get the following error:

[17179570.272000] 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.

How do I boot with the 'noapic' option?

I found a similar type problem on this forum here:
http://www.linuxquestions.org/questi...d.php?t=499929
Which I thought would help me because I have a similar Mobo M2NPV-Type from ASUS.

This post, however, doesn't tell me how to "boot with an option" (I'm a newbie as you might have guessed)

greetz,
Marvelade

If you can get into and edit the bootloader configuration, then you would have a line near the start of the bootloader like the following:
append="noapic"

And that will make it happen every boot.
Meanwhile, to simply get the machine up and running, you need a boot: prompt, such as when you first arrive at the boot menu after turning on the machine. At the boot prompt you would enter your kernel name, followed by 'noapic', like: "boot: vmLinuz root=/dev/hda1 ro noapic" or "vmlinuz noapic" or similar. Check the manual for LILO or documentation for GRUB, depending which you use.
If you can find no way to get at a boot prompt, you may need to stick in the install CD, and use that to boot your system, with a command very much like the one above.
Change /dev/hda1 to match your own installation location, and adjust the name of the kernel's bootable image to whatever yours is (on Ubuntu it is sometimes 'casper' maybe, but I am not sure; it could be called something like 'linux-2.6.14')

I have GRUB set up to show a menu to choose between
- Kubuntu Linux 6.10 (hdb) which boots into KDE (at least: up till yesterday :s now I just get the error)
- Kubuntu Linux in safe mode (hdb) which boots to a "root@xxxx~#" prompt
- and last/least: Windows XP (hda)

I guess I could boot to a command prompt and use an editor to add the line 'append="noapic"' to the grub.conf file (althougug I think it's called differently... something with "list" or "lst"...). I guess I add it to the linux part of that file or do I put it at the very end or beginning??

I do not get a "boot:" prompt.

Best regards and big thanks for your help so far.

Code:

To pass the option noapic, you press 'e', in GRUB, on the boot option you want to edit. Then, press 'e' again on the line that start with kernel. Append "noapic" (without quotes) at the end of the line. Press Enter, then 'b'. It should boot fine.

To make the change permanent, you will need to edit to /boot/grub/menu.lst file. Here how to do that:

$ gksudo gedit /boot/grub/menu.lst

Now, find those lines:
## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash

Add "noapic" to defoptions (do not uncomment it):
# defoptions=quiet splash noapic

Save and close.

Finally, generate you new menu.lst:
$ sudo update-grub
