Distribution: compiled under Debian Etch 4.0 (AMD64 version)
Hardware Environment: ACER aspire 5050-4697 (AMD64 laptop)
Problem Description: with ACPI enabled as in distribution kernel the machine blocks at boot up. Disabling acpi, and cleaning modules, the following config
allows to boot and have some acpi
# CONFIG_ACPI_SLEEP is not set
# CONFIG_ACPI_PROCFS is not set
# CONFIG_ACPI_AC is not set
# CONFIG_ACPI_FAN is not set
# CONFIG_ACPI_BAY is not set
# CONFIG_ACPI_PROCESSOR is not set
# CONFIG_ACPI_CUSTOM_DSDT is not set
# CONFIG_ACPI_SBS is not set
Battery not found message (but the battery is there!), SBS module can be loaded but solves nothing.
AC module locks the kernel.
Steps to reproduce: compile kernel (under x86_64 linux) as it comes from repository (select AMD64 generic procesor). install, reboot
on ACER Aspire 5050-4697 or compile with above configuration plus AC driver, hide the AC modulo at boot time and modprobe it to block kernel.
Please attach the acpidump and dmesg output.

This is dmesg output when running Ubuntu i386 (kernel 2.6.20-16-generic)

This is dmesg output form Sabayon LiveCD (kernel 2.6.22-sabayon)
This is the dmesg output when running the LiveCD of Sabayon 3.4f (kernel 2.6.22-sabayon). I had to use the option acpi=off in order to make the kernel initialize. It is the same output when Sabayon was installed in my laptop.
Exactly the same problem, but a different model: Acer Aspire 5050-4872, originally with Linpus preinstalled. ACPI works fine in kernel 220.127.116.11 in version i386, but it does not work in version x86_64. It does not work in any kernel upper than that.
