Kubunt freezing when networking interface not connected.

[Guest]

Hello and thanks for reading my thread,

I'm having a problem here. I did a fresh install of kubuntu, and this computer will only boot properly (without freezing) when it is not plugged into a network via ethernet cable. It will also freeze when I unplug after a successful boot. I have had the same problem with Ubuntu... I have done a little bit of searching to no avail. Any direction will be appriciated. Where do I start?

Some of this information may help.

operating systems. In addition to loading the Linux kernel,
it implements the Multiboot standard, which allows for flexible loading
of multiple boot images (needed for modular kernels such as the GNU Hurd).

Re: Kubunt freezing when networking interface not connected.

There really isn't enough to go on in your post.

Where in the process is it "freezing"? - try hitting ESC if you're getting a boot splash or edit grub and remove splash.

What does your boot.log file say?

What do your log files say about the "freeze" when you pull the network cable?

You say it's a fresh install, but what version? (K)Ubuntu hasn't used grub-legacy (version 0.97) since 8.10 or 9.04.

Does another (non-debian based) distro work OK or have the same issues?
