Bug 9088 (Hernan)

Summary: ACPI several problems on ACER 5050-4697
Product: ACPI Reporter: Hernan G Solari (hgsolari)
Component: Config-OtherAssignee: acpi_acpica-core (acpi_acpica-core)
Status: CLOSED DUPLICATE    
Severity: blocking CC: aom1967
Priority: P1    
Hardware: All   
OS: Linux   
Kernel Version: 2.6.22.8 Subsystem:
Regression: Yes Bisected commit-id:
Attachments: 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)

Description Hernan G Solari 2007-09-27 05:35:03 UTC
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.

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.
Comment 6 Arturo Ovalle Mendoza 2007-10-13 19:48:16 UTC
Exactly the same problem, but a different model: Acer Aspire 5050-4872, originally with Linpus preinstalled.  ACPI works fine in kernel 2.6.20.16 in version i386, but it does not work in version x86_64.  It does not work in any kernel upper than that.
