           Summary: ACPI several problems on ACER 5050-4697
           Product: ACPI
           Version: 2.5
     KernelVersion: 2.6.22.8
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: ACPICA-Core
        AssignedTo: acpi_acpica-core at kernel-bugs.osdl.org
        ReportedBy: hgsolari at gmail.com


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=y
# CONFIG_ACPI_SLEEP is not set
# CONFIG_ACPI_PROCFS is not set
# CONFIG_ACPI_AC is not set
CONFIG_ACPI_BATTERY=m
CONFIG_ACPI_BUTTON=m
CONFIG_ACPI_VIDEO=m
# CONFIG_ACPI_FAN is not set
CONFIG_ACPI_DOCK=m
# CONFIG_ACPI_BAY is not set
# CONFIG_ACPI_PROCESSOR is not set
CONFIG_ACPI_NUMA=y
CONFIG_ACPI_ASUS=m
CONFIG_ACPI_TOSHIBA=m
# CONFIG_ACPI_CUSTOM_DSDT is not set
CONFIG_ACPI_BLACKLIST_YEAR=0
CONFIG_ACPI_DEBUG=y
CONFIG_ACPI_EC=y
CONFIG_ACPI_POWER=y
CONFIG_ACPI_SYSTEM=y
CONFIG_X86_PM_TIMER=y
CONFIG_ACPI_CONTAINER=m
# 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.
