Did you also try to figure out if this error occurs with Debian and a 
new kernel? The kernel itself is really stable although there's a new 
release every 2-3 months.
I tried to install many different Linux kernel, because I first thought 
that the error is a kernel problem but than I figured out that the 
problem is Ubuntu specific.
I used another partition to install Debian Lenny on it. Then I installed 
a self compiled kernel from kernel.org to install it on Lucid and Lenny. 
As it seemed to work properly with Lenny and while the same error 
occurred with Lucid I knew that the problem is at Lucid.
This week after checking for new updates I found and update for 
acpi-support. That made me watching more.
After reading the changelog 
<https://launchpad.net/ubuntu/+source/acpi-support/0.136.1> and I 
thought that this may also fix my problem. So I downloaded the source 
and tried to add those pieces of code which were added to 
/etc/acpi/power.sh. To ensure that the new pieces of code will be used, 
I restarted the system and tried to plug in the battery an plug of the 
AC/DC-Adapter. The system did like it did before.
Now, after installing the whole update I try again and will post this here.
