[Bug 34794] GDM won't log in with ACPI enabled (Travelmate 3000)

Affects: gdm (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I have an Acer Travelmate 3002WTMi laptop with Ubuntu 6.04 "Dapper
Drake" installed. I boot successfully with the following boot options:

root=/dev/hda1 ro noapic nolapic vga=771 pci=noacpi quiet splash

But my soundcard does not seem to work with the 'pci=noacpi' option. If
I remove this option, the kernel boots fine, and I get the gdm login
screen as usual. But GDM is a bit slow, and when I enter the username
and password (and press enter), it seems to take a break when loading
the rest of the desktop. I can move the mouse pointer, and the login
sound (the drums) seems to be locked in a loop. The sound does not stop
before I manually kills ESD. The only thing I see on the screen exept
from the mouse pointer is the brown background.

If I kills the X session with Ctrl + Alt + Backspace, X restarts and
tries over agan (and fails).

I can switch to another terminal (Ctrl + Alt + F1 etc) and log in from
one of those (in text mode), and use command line tools as usual.
Everything is quick and responsive here, and the kernel itself seems to
be happy enough without the 'pci=noacpi' boot option.

I hope this bug will be fixed before the Dapper release, because I am an
Ubuntu enthusiast, and have used Ubuntu on this machine from the verry
first day I had it, but I have never got sound working until now
(neither have I been able to boot with ACPI disabled until now). It
seems like my soundcard (Intel HDA controller) needs ACPI enabled to
work.

Just tell me if you need more information, logs, etc.
