Public bug reported:
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.
