    Today's kernel update has done me in...

    Attempting to use 7.10 (64) Kubuntu on an AMD 64 X2 HP Box.

    Adept Updater indicated that there were 3 new updates (28 MB) were available.

    All three implied that they were kernel updates. Installed same.

    System continued to function just fine.

    Did an orderly shutdown and rebooted.

    Screen now only displays the following:

    [some numbers] MP-BIOS bug: 8254 timer not connected to IO-APIC
    [some numbers] kernel panic - not syncing to IO-APIC + timer doesn't work! Try using the 'nopic' kernel parameter

    Now what do I do?

    I can be considered as a noob so please be gentle.

    Reboot. When you are at the Grub Boot menu, press F6. Use your right arrow key to move to the last option. Press the spacebar and type noapic and then move the cursor all the way to the right and press enter. If this does allow you to fully boot into your system and you get to the desktop, you will want to edit your /boot/grub/menu.lst file to make this change permanent. Post back with your results.

      Alas, as Grub in counting down it ignores the F6 key press and times out displaying the same screen as before.

      Do you have anymore ideas?

        You mention count down. So this isn't a live CD? If not, during count down, press ESC. There you should be able to edit the GRUB entry to add nopic.

          Sorry, no it isn't a live CD. Pressed ESC, was presented with a menu - selected recovery mode - bunch of stuff flashes across the screen and ends with a root@... prompt.

          Sorry, I don't know what to do next.

          Thanks for your reply.

            Re: Today's kernel update has done me in...

            Ok, I got brave and, after reading some stuff, added, using nano -w, the following lines to the /boot/grub/menu.lst:

            ## nopic
            ## e.g. nopic=true
            ## nopic=false
            # nopic=true

            Rebooted and the system returned the same, original error.

            What is it I don't understand (other than everything)?

            I'm stumped.

              From the point after pressing ESC, it should still be at the default choice for boot. Press "e". This will let you edit the boot options for that selection. Arrow down to the next line and press "e" again. Go to the end of the line (you'll know you have the right one because it will read "quiet splash" ) place that entry for nopci there separated by a space. Press ESC, and if I'm not mistaken, press "b" to boot from there.

                Success! At least partial. The system boots fine with editing the default item.

                I noted that in my original msg I missed spelled "noapic" (omitting the "a") once corrected it worked.

                Now could some kind soul tell me how to get this "noapic" embedded in the boot sequence? I corrected the spelling in the bit I inserted into the /boot/grub/menu.lst (above msg) but it still doesn't work.

                Thanks for your help

                  Once in Kubuntu and logged on as you. The way to edit that file is as root. That is a must in order for the changes to take. Usually I open Konqueror by Alt-F2 typing in kdesu konqueror. Once open, browse to that file location, right click on it and choose "Open With" and choose Kate. Make the change, save close out Kate and Konqueror. Do nothing further with Konqueror, close it once finished with this task.

                    As I wrote earlier I have edited the file. I managed to save the changes - with what I guessed to be the correct change and format.
                    What the problem is what exactly do I edit into the menu.lst file and does it make any difference where I put it?

                    Cheers,

                    Harry

                      Sorry. It should be very similar to what was done at the GRUB menu when you "fixed" it there. That is a temporary modification to the menu.lst file. Add that command to the same line that appears in that file. Again, that line will usually end in "quiet splash".

                        Complete Success!

                        Thank you so much for you perseverance.

                        Just as matter of curiosity what is "noapic"?

                        Regards,

                          acpi=off is a Linux command that switches off <Advanced Configuration and Power Interface>, whilst noapic is the Linux command that disables the <Advanced Programmable Interrupt Controller>.
