Ubuntu 12.04 crashes if lan cable is pulled out from emachines laptop

Asked by Link

Hello

I'm running Ubuntu 12.04 on an emachines G625 Laptop. But, Ubuntu is only working if an lan caple with internet connection is plugged in.
This means: If the lan cable gets plugged out (and the computer notices this - with showing a disconnect message), the whole system freezes. I can only move the curser, but doing nothing with it or something else (like open a program with the cursor, or with a shortcut).

The problem appears after logging in to the standard ubuntu user interface. The start screen is working without an internet connection.
I can see only the background image after logging in without internet connection.
The same problem appears in the "user defined session".
Ubuntu 2D works without an lan cable connection, and also the console session.
But in Ubuntu 2D, the wireless lan doesn't work. The available connections are displayed, but the computer can not connect.

Before Ubuntu 12.04, i had Ubuntu 10.04 installed on this emachines laptop. 10.04 didn't have this problem.
I installed 12.04 with upgrading 10.04, and also with installing it from an live usb and live cd. Nothing makes a different.

I suggest you report a bug.

Does it happen in the liveCD session of Precise?

Yes, i wanted to report a bug. I couldn't find a other way to report this bug, which concerns the system, and not to a single program.

It happens on the installed system (installed on a partition of the hard drive), and also on the live system (i tried it from CD and USB stick).

Besides, on an other partition of the system Windows Vista is installed. But i don't think that this affects the running Ubuntu and could cause this problem.

Run:

ubuntu-bug network-manager

And report the bug. The devs can move the bug if it is associated with the wrong package.
