Ouch!

> After the upgrade to 1.1.3 my EeePC 701 4G freezes on shortly after
> setting the console fonts with a garbled screen (no more readable,
> looks like lines being out of sync or so). I have to power it off by
> pressing the power button 4 seconds. No more ping, nothing. Due to the
> garbled screen, I do not know if there was any kernel panic or so.

> It does not happen if I:
> 
> * unplug the power supply (not very usable).
> * boot with acpi=off (neither very helpful)
> * downgrade to version 1.1.2 (did that :-)
> * boot with init=/bin/bash (of course)
> 
> It does happen:
> 
> * independent of the kernel (tried 2.6.30, 2.6.31, 2.6.31 from grml,
>   2.6.32)
> * independent of the udev or console-setup versions (downgraded both
>   to the versions in testing since I first suspected them)
> * even when I boot into single user mode (and power supply is plugged
>   in)
> * as soon as I plug in the power supply (in case I had it unplugged on
>   startup) the system freezes and garbles the screen, also if running
>   under X.

The last point lights a bulb. May be this is related to the 
SuperHybrid thingie? Perhaps setting it to 'normal/overload' breaks on 
701s?

There are a couple of settings in /etc/default/eeepc-acpi-scripts aout 
it. (See the commented file in 
/usr/share/doc/eeepc-acpi-scripts/examples)
