regression: acpi not working since upgrade from feisty to Gutsy

[Bryan]

Binary package hint: acpi

I have a Dell Latitude L400. Ever since the install of tribe 5 I have not battery information. The power usage is unavailable and proc reports that my battery is not present. I get the following (incorrect) message from dmesg:

ACPI: Battery Slot [BAT1] (battery absent)

It also reports that the AC adapter is "online" though it is currently unplugged.

ACPI: AC Adapter [ACAD] (on-line)

Furthermore, the temperature always shows a constant 50C which is incorrect. This could become a very serious problem because it will allow the computer to overheat under load. All the fans stay off until the temperature reads 65C...

All this worked under feisty.

I compiled a vanilla kernel version 2.6.22.9 and acpi works. I used the
vanilla sources from kernel.org and the config file
from /boot/config-2.6.22-12-generic. There was an error message
involving a missing acpi file which I assume is related to a
debian/ubuntu patch.
this was the symbol the vanilla kernel didn't like from line 18:
CONFIG_ACPI_CUSTOM_DSDT_INITRD=y
I saw a few rumblings about this when I googled for acpi problems, but
they all involved older kernels.

What kernel version is the gutsy image based on? It looked in the
changelog like they maintain their own patch-set against 2.6.22, but
that doesn't seem right... Can someone clear this up for me?

I guess I have a workaround of sorts, but I don't know if the vanilla
kernel will break any Ubuntu features. I remember in Fedora Core it
caused all sorts of problems... It seems fine here. I would love to be
able to use the stock kernel.

I can confirm this on my latitude l400. I have my cable unplugged for the past number of minutes,

I should say that I've hacked the dsdt a little, in order to fix a couple of warnings.

I'm bitten by this one, too. I'm running BIOS A05, btw.

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
