Ok, this is a strange one. I've got a Dell Inspiron 5000e. Recently
something happened to ACPI and now 'shutdown -p' doesn't switch the
power off anymore.
Looking at dmesg I see:

Is is that acpi isn't loading properly?
What is very strange is that for the first time suspend/resume appears
to be working. The first time I shut the lid the machine stays on and
just the screen powers down, but the second time (and subsequent times)
the machine completely suspends including the fans and harddrive.
Is it the bios that is doing this? It's never worked before - I'd say
that you guys have fixed ACPI and that's why it is working, but why does
-p not work then?
