[hardy] Slow boot up

[Giovanni Condello]

Ubuntu Hardy slowly boots up. System seems to hang for about 30secs just after the "Waiting for root device" phase (maybe during the harddisk recognition?)
This happens on a cold start (system previusly off) with or without splash screen and also during reboots if splash screen is on.
See attached videos for details.

Ps. I had wrongly related this bug to usplash, but now i'm not so sure that he is "guilty"

Thanks for your bug report and for your contribution to ubuntu. In order to help fixing that bug, can you provide the following informations?

 1. The file created by this command on a terminal : lspci -vvnn > lspci-vvnn.txt
 2. The output of this command on a terminal : cat /etc/usplash.conf
 3. The output of this command on a terminal : uname -a
 4. The actual resolution of your screen while using your computer

The splash hangs at "Mounting root filesystem" stage (discovered by leaving splash on and quiet off)

[Saivann Carignan (oxmosys)]

Thanks for providing these detailed informations, can you also attach the output of /cat/usplash.conf? You just forgot that little one. You also say in the description that ubuntu boot without any problems when you remove splash, is that right? Also when usplash seems freeze for ages, does it finally boot after some time or does it hang there permanently? I think that updating the description of the bug to be more descriptive about that point would be helpful for developers. Thanks for being active on your bug report!

I'm making a couple of vids of the boot-up, so that devs can see whats going on. It seems that it hangs also without the splashscreen. I will update the description and summary as soon as I can confirm this.

[Giovanni Condello (nanomad)]

Well, it seems that i was wrong. The slowness appears also without the bootsplash on a cold start. The video i made makes things clear

[Saivann Carignan (oxmosys)]

Great! Thanks for working on this. Can you boot your computer without splash and quiet and take a photo or a video of the console outputs that appears during a very long time during the time your computer is booting? This should give us more information about the problem.

I run Hardy, I don't think my bootup is so slow, but I think its slower than *a certain other* operating system on my computer.

[Saivann Carignan (oxmosys)]

Thanks for all the time you took to improve that bug report. Your bug report has already been reported as bug 190414 so I will mark this bug as a duplicate of this one. It would be very great if you can attach the following informations to that bug, this will really help kernel developers :

1. uname -a > uname-a.log
2. cat /proc/version_signature > version.log
3. dmesg > dmesg.log
4. sudo lspci -vvnn > lspci-vvnn.log

Also an additional workaround that should work for you : To avoid that very long boot time, add "clocksource=hpet" (without the quotes) to your ubuntu kernel boot line. If it works, you can apply it permanently by editing your /boot/grub/menu.list file.

Same here.
clocksource=hpet speeds up things but doesn't solve the problem.

Gutsy was booting really faster.

I have Kubuntu 8.04 Hardy Heron (KDE 3.5.9) and it has become dead slow (>4mins) at boot (at the "reading files needed to boot" stage) after a couple of updates a few days ago. Adding clocksource=hpet to my kernel line hasn't solved this at all. I've opened up a thread at http://ubuntuforums.org/showthread.php?t=800878 with some debug info. Could someone please take a look and see if I need to file a new bug report? I'm a total noob and would really appreciate any help in solving this. Thanks a ton!
