Kubuntu/Ubuntu: "hda-intel: spurious response" on Intel Atom and D945GCLF

If you are going to install Ubuntu / Kubuntu on an Intel Atom based computer with the D945 based chipset; be aware that there is a bug in the linux kernal which leads to printing of following line continuously on screen, preventing you from logging-in. Sometimes when you reset the machine, it goes away but not at most of the times.

       hda-intel: spurious response 0x0:0x0, last cmd=0x000000       

The error looks as if it's from the sound driver; but the workaround for it is in the graphics department :)

In the BIOS setup, Video Settings, Set the IGD Aperture size to 256MB (The default is 128MB; in which the above error occur).

P. S. You can get to BIOS setup by pressing F1 key at computer startup.

Getting ZTE MF100 from Mobitel Lanka to work on Kubuntu 10.04

It's much easier than you would imagine. You need not use "wvdial"; the KNetworkManager works like a charm. This should work the same for other plug and play 3G modems by Sri Lanka Mobitel and Dialog too.

First; plug in your MF100. Kubuntu would auto detect the modem and show a mobile icon in the system tray. If you are already connected to a network, the icon would appear in the context menu of the KNetworkManager like below.


Click on "Mobile Broadband - Create network connection" to get the following dialog


Fill the information as follows:

Connection name: any name
Connect automatically: check "Connect automatically" if you wish to establish the connection automatically when you plug the modem

In the Mobile Broadband tab:

Number: *99#
User name: anything but blank
Password: anything but blank
APN: "mobitel3g" (without quotes) for Mobitel. I think for Dialog it's www.dialogsl.com please verify.
Type: Any (try "Prefer 3G" or "3G UMTS/HSPA" if you have better 3G reception

Leave other fields as they are.

In the PPP tab:

Check "PAP" under Authentication and de-select every other option.

Click OK to save settings and connect to the internet, and if you did not use auto connect; you'll have to click the icon in the system tray to activate the connection.

It's that simple! :)
