Bug Description
ABOUT ME AND MY COMPUTER;
I'm Dutch and 15 years old so sorry for my bad English and I'm pretty new with Linux coding. I could miss some important information or investigation info results, please ask them if you need so...
I have an home-made game computer and I've installed Karmic Koala alpha 3 on it and updated with the "stable" updates. I'm using the 2.6.31-4 kernel but I've also noticed the following problem on the 2.6.30 kernels. I've never done something weird with Ubuntu parameters and settings or whatever.
THE PROBLEM;
Ubuntu starts good until about 9-10 seconds, but stays there for 50 seconds. After that he finishes the boot in 2-3 seconds.
I don't think that's normal... Is it?
THE THINGS I'VE TRIED
I've detached all external devices and booted again, same results. So I've ran bootchart an I get a graph but it doesn't make any sense to me, I've attached the graph. I've ran lspci and dmesg in the terminal but the only thing I see that could be the problem are the
"Buffer I/O error on device fd0" lines but that doesn't say anything to me either. I don't even know what the device fd0 is perhaps anyone can tell me?
WHAT I SUSPECT THE PROBLEMS COULD BE;
*When I start Ubuntu in a tekst based mode I see; "Buffer I/O error on device fd0" a couple of times after each other. Perhaps there's the problem...
*I have an onboard Intel video card. Perhaps that's conflicting with my Nvidia GTX 260 graphics card (with installed driver)...
*I could have a bad Ubuntu install....
THE FIX;
I don't know. I'm a kind of stuck here. I hope you guys can fix it or tell me what might could be the problem.
I've attached the lspci and dmesg output in 1 file and the bootchart graph in the other.
If you need more info please ask. And please say it to me if I'm doing stupid things.
Good luck.

I observe similar symptoms on my Sony Vaio notebook. I installed every version of Ubuntu since 6.x. Now I upgraded to Karmic using update-manager and booting got at least two minutes longer, or maybe more.
As far as I understand, the reason in my case is the following:
- the notebook has one bay in which either DVD drive device or a floppy drive device can be inserted.
- I keep DVD drive in the bay
- during booting, the BIOS reports the existence of the floppy
- something in Ubuntu recognizes that floppy as a device exists and wants to access it
- that same thing doesn't want to let booting continue before the floppy answers!
- floppy never answers.
