    Bootchart showed some interesting things. I'll have to mess with it when I get home.

    Bootchart:

    Angry Re: Slow boot after upgrading to 11.04

    Btw, did anyone of you try to use banshee? That program must be a joke (buggier then Win95 was).

    Ubuntu 10 was such a good piece of cake that Canonical seems gained an over-confidence, beliveing they're kind of a messiah who's gonna revolutionize the PC industry. However most of their new stuff seems to be sole sophistry, so at the end of the day they just wanted to poop bigger than their hole is.

    I'm sorry to say that, but I'm so disappointed about 11.04.

    Re: Slow boot after upgrading to 11.04

    I think I found a solution:

    in /lib/udev/rules.d/60-persistent-storage.rules

    comment out rule:

    # ATA/ATAPI devices (SPC-3 or later) using the "scsi" subsystem
    KERNEL=="sd*[!0-9]|sr*", ENV{ID_SERIAL}!="?*", \ SUBSYSTEMS=="scsi", ATTRS{type}=="5", ATTRS{scsi_level}"[6-9]*", \ IMPORT{program}="ata_id --export $tempnode"


    then run as root
    Code:
    update-initramfs -u
    reboot, and check your booting time
    Here is my new bootchart:

    use linux

    I just tried using bootchart myself, and it looks like rebooting or booting from a shutdown state give quite different results.

    Have you tried cold-booting as well after making that udev change?

    Not as of yet. Will try when I get home tonight.

    Question Re: Slow boot after upgrading to 11.04

    Wow, what does this rule exactly do? I googled but don't really understand what's being changed.

    I'm not sure either. I'm guessing it has something to do with the way the OS interacts with the drive during boot. There really isn't any info available.

    Thank you, this helped speed up my boot time from 70+s to about 37s (29s from GRUB to login window, 8s from presssing enter to full desktop; used to be 30+40+).

    Now I just have to figure out how to reduce those initial 30 seconds.

    I was struck by the same problem AFTER I had my broken mainboard switched to another model. This solution here fixed it for me too, but I am left a bit curious as to what I just commented out. Would rather not find out weeks later that it was something rather important

    Re: Slow boot after upgrading to 11.04

    Running Linux Mint Katya. Haven't done the bootchart yet, however with the old stop watch I was having 1:48 second boot. After performing what this post said, my boot is down to 42 seconds.

    I would also like to know just what this does, but much happier even not knowing...thanks for the post!
