Acer Aspire One freezes on Kubuntu 12.04 boot

[benjamin]

According to the X Freeze Troubleshooting documentation "It's best to file a new bug report rather than joining onto someone else's", so here it goes:

I have installed Kubuntu 12.04 from USB on an Acer Aspire One. After installation, the computer freezes on boot after logging in the user.

The CD and USB are still with me, however at this moment the computer is remote (I installed it for someone who had to leave, please mind this while answering, as I will have to guide this person remotely, who knows little about operating systems etc.).

Since the computer is remote, I have not the possibility right now to "Reproduce the freeze, and with your system frozen ssh into it (over ethernet) and collect:
 * dmesg > dmesg.txt
 * /var/log/Xorg.0.log
 * /sys/kernel/debug/dri/0/i915_error_state [Intel graphics only]

Would you please instruct me on "ssh"-ing into the frozen system?

Q: Have I experienced just one lockup, or have you had a series of these lockups?
A: I have experienced a series of lockups.

Q: If you've had several, how often does it occur? Every few hours? Once or twice a day? Couple times a week?
A: At every single boot after logging in.

Q: When did you first notice it?
A: Right after installation.

Q: Under what conditions does it seem most likely to reproduce?
A: Only at boot time, I cannot pass the splash screen.

Do you need more information? Please help, I've messed up my friend's computer trying to promote Ubuntu. I hope I can fix this rapidly so this person can go back to work.

PS: thanks for all your work on Ubuntu / Kubuntu!

BIOS settings changed to set Network boot as first in boot device priorities stops the freezing of the OS.

What puzzles me is why disabling network boot completely in BIOS did not.
