Bug Description
Although Feisty runs fine in my Sony Vaio PCG-K115z laptop on ac power or batteries, I can only boot to Gusty if the laptop is running on battery.
If I try to boot with ac power the system crashes some seconds after GDM is loaded. And, if I boot on battery and, after the system is loaded, I plug the ac power, the system crashes instantly.
The only way to boot on ac power (or to plug it after boot on battery and keep the system running) is to set acpi=off in the kernel line. I've tried to check the acpi configs and events triggered by the ac power, but could not find any problem. I've also forced the crash plugging the ac power after system load to check system logs for that second, but nothing is registered.

The same model as above, except for me it does not work even if the laptop is run on battery power. However, running with acpi=off/ noacpi affects useful areas like wireless interface.
Note that in my case GDM is able to load when booting with kernel boot option "acpi=ht".
