acpidump + dmesg + dmidecode + interrupts + lspci

On my Dell Latitude D630, I've several problems with the acpi since some Linux
versions:
# HAL crashes at boot, see the logs:
http://bbs.archlinux.org/viewtopic.php?pid=713412#p713412
# Xorg crashes randomly without logs.
# Often I've a kernel panic during the boot

With acpi=off, it works correctly, but without the power management and only
one CPU :-/

I've posted a bug report on the Arch Linux bug tracker.
After some questions from a developer of Arch Linux, he recommends me to fill a
bug on kernel.org.

You can read our discussion here: http://bugs.archlinux.org/task/18445

Since this discussion, I've tested several version of the Linux kernel (2.6.32
- 2.6.33 - 2.6.34), especially with the vanilla version:
http://aur.archlinux.org/packages.php?ID=24450

I've the same problem, except with the 2.6.30 version.

After the reading of this web page:
http://www.lesswatts.org/projects/acpi/debug.php I've tested all options.

The bug disappears with the "nolapic" option at boot.

Now, I've the status of my battery, but I still have only one CPU, instead of
two CPUs.

I can provide some logs or tests.

BIOS version: A17
Linux kernel: 2.6.34

Thanks for your support.
