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.
