This got zero response under general help, so I'll try the noobie area. After all, some may call this a noobie question.

9.04 freezes during boot
I'm a bit of a noob, so please forgive any noobieness to this post. However, I did search quite a bit before starting a new post.

Here's my problem. Occasionally (so not every time), Ubuntu freezes during boot. In order to get it moving again, I can push 'Enter' or one of the arrow buttons. Unfortunately, I have to do this many times or it just sits there. Also, I can't just hit one of those buttons each time if freezes, because it doesn't always work. In other words, I sometimes have to wait a few seconds and hit the buttons again.

Before this started, I had a nice startup time of about 65-70 seconds. Now, it may take 2-3 minutes. Speed is not my biggest concern here, but I would like to have my zippy machine back on a consistent basis. My biggest concern is some possibly bigger looming problem with who knows what, but I have run diagnostics on the hardware, and nothing appears to be wrong.

Thanks in advance for the help.

Hi! It would be helpful also if you could post the hardware specs of your computer.

In your System Monitor (System > Administration), what process takes up a lot of CPU usage?

OK, system is an HP with AMD Turion & 3 GB of ram & 150 GB hard drive. The Ubuntu version is 9.04, Kernel Linux 2.6.28-14-generic, GNOME 2.26.1.

The gnome-system-monitor takes up about 10-15% and firefox takes up about 2-3%, but I don't think that matters. The real issue is that often (about 65% of the time now) when I start up the system, it hangs up at the Ubuntu splash screen. I suppose it would finally get going on its own, but my impatience has led me to figure out that pressing 'Enter' or the arrow buttons sort-of kick starts it into continuing. Once the system gets booted up, it seems to work OK. I'm just worried that there's something worse going on.

How do I fix this, and should I be concerned?

Disable splash try to see where it's hanging open up terminal and type
sudo gedit /boot/grub/menu.lst remove quiet and splash entries

see if you can get a verbose start-up report and/or log

if you watch the verbose you might see what's hanging

OK, how do I get a verbose startup report/log? I see many logs under System Log Viewer, but I don't know which one to use.

Hey try this, go and

sudo gedit /boot/grub/menu.lstand where it shows your kernel at the very bottom, the line should look similar to

kernel /boot/vmlinuz-2.6.27-14-generic root=UUID=1886BA2586BA0374 loop=/ubuntu/disks/root.disk ro ROOTFLAGS=syncio quiet splashadd this line onto the very end of that line:

acpi=noirqso it will finally look like this:

kernel /boot/vmlinuz-2.6.27-14-generic root=UUID=1886BA2586BA0374 loop=/ubuntu/disks/root.disk ro ROOTFLAGS=syncio quiet splash acpi=noirqThat should stop you from having to hold a button. Call me a liar if that doesnt work.
