    686 kernel slower to boot?

    Hey ya'll... I just got around to upgrading my kernel to 686 from the default 386 that my live cd installed. My machine (pentium m notebook) is much peppy-er once it's going, but the boot takes twice as long, stalling and sputtering, and going black with a cursor in the top left corner for 20 seconds right before the splash screen. I don't want to downgrade unless I have to... but this boot-time is sad.

    Any thoughts?

    Thanks.

    Re: 686 kernel slower to boot?

    Normally, the boot process is accompanied by a string a of messages flying by as the machine boots up. Which messages are staying around long enough to read?

      those fly by a little more slowly, but acceptably... it's when that is done, before the transition to the splash screen. A black screen comes up with the cursor in the top right corner... and hands for like 30 seconds, sometimes longer. Then the splash screen does its thing... and up comes the desktop (and then I'm in heaven).

      thanks for the note.

        Take a look at the file /var/log/dmesg. You can see the same information, if you're comfortable in a konsole with the command "dmesg | less. You might also want to look at kdm.log because it seems like your problem is taking place very late in the boot process.

          thanks again for helping... I have to admit, i haven't a clue what the data i found represents.
          I'll paste it in case it is more meaningful to you. If it makes your head hurt too, I apologize in advance.

            I'm sorry to say that your dmesg file is as incomprehensible to me as my own. The part that you posted is the first part (ending with the kernel command line). Since your problem starts at the very end of the boot process, I would think that, if the problem is going to be visible in dmesg, it would be in an error notation in the last ten or fifteen lines of the file, or at least that those lines might refer to whichever system is failing. Also, did you take a look at the "kdm.log.1" file? Mine is very short (just one line). If yours is longer, it might indicate a problem.

            My other thought is that the problem might be in one of the shell scripts that are executed between booting the kernel and starting the xserver. Usually, though, these scripts just fail and the machine winds up in recovery mode. The only things I can think of that might delay you without failing completely are network setup or mounting peripherals. Perhaps someone who knows more than I do can come up with something more specific.

              Yeah... i didn't realize the feedback was so long. There aren't any errors in it, there may be somethign askew, but it isn't obvious.

              I'll keep looking... thanks for the time.
              best.
