Dell inspiron duo crahses when plugging or unplugging the power adapter

[emarco]

I have a Dell inspiron Duo and installed Ubuntu 11.10 on it by using wubi. When I plug or unplug the power adapter the system crashes, dumping a lot of messages in a dark screen and halts. The only way to recover it is to power it off by maintaining the button pressed.

Following a recommendation given in the forum, I downgrade the package pm-utils to 1.3.0-1ubuntu1 (Lucid version) replacing the updated version 1.4.1-8ubuntu1 (Oneiric Ocelot) and the problem disappeared. General information:

After some time, the problem re-appeared, so the walk-around of downgrading the package pm-utils didn't work. Following another recommendation, I deactivated ACPI and this time the problem did disappeared.

This is a big problem, because I have to shutdown the machine to connect the AC Power Cord

This seems to effect every Distribution using the version 3 kernel.

Anything I've tried using the previous version 2.6.x kernel doesn't have the problem.

I don’t know why this was converted into a question, it seems to be in fact a bug, and a quite serious one.

I can confirm this with my Dell Duo.

From what I can tell from the kernel bug, it seems to be a broken DSDT. Maybe Ubuntu could ship the corrected one?

emarco, thank you for reporting this bug to Ubuntu. Oneiric reached EOL on May 9, 2013.
