[olug] ACPI Under Linux

[Brian Wiese]

Has anyone else had any experiences successes/failures with ACPI in Linux?
 I guess its like the new kind of advanced power management for
motherboards.

ACPI Project on Sourceforge
http://sourceforge.net/projects/acpi

Do you have any more pertinent info to post Joe?

thanks
Brian

|I bought a new 1.2GHz computer locally from DIT.  I'm dual booting to 
|Win98SE and RH7.3.  Everything works fine, except under Linux the system 
|appears to hang after being unattended for about an hour and a half.  I 
|suspect ACPI is causing the apparent hang and it has actually gone into 
|some sort of a suspend state from which Linux can not recover and of 
|course the disk gets trashed.  I'd prefer to turn off ACPI all together, 
|but the AMI bios isn't capable of disabling it.  Win98 works fine and 
|doesn't have any problems.  I use my linux box for web development 
|primarily, but I'm considering using Windows instead 
|(Apache/Tomcat/PHP/MySQL) and dropping Linux.  I've been using RH Linux 
|since version 5.0 and would like to keep it, but growing tired of the 
|wrestling match trying to get it working.  This has been an ordeal since 
|late May when I decided to upgrade my old RH6.2 system and the reason I 
|bought the new computer.
|
|Has anyone bought one of these computers and got it to run as a server 
|(able to run unattended for days)?  Any suggestions on how to proceed?
|
|Here's what I've done/found so far:
|
|System Description:
|-------------------
|
|    CPU: 1.2 MHz Duron
|    MEM: 128 MB
|   DISK: 40 GB (20GB Win98SE/20GB Linux)
|     MB: Gigabyte GA-7VKML
|   BIOS: AMI
|
|
|What I've done:
|---------------
|
|1. Installed RH7.3 (kernel-2.4.18-3)
|2. Upgraded to kernel 2.4.18-5
|3. Upgraded to kernel 2.4.18-10
|4. Rebuilt kernel turning off APM and turning on ACPI
|    Here is excerpt from .config file:
|       CONFIG_PM=y
|       CONFIG_ACPI=y
|       # CONFIG_ACPI_DEBUG is not set
|       CONFIG_ACPI_BUSMGR=y
|       # CONFIG_ACPI_SYS is not set
|       # CONFIG_ACPI_CPU is not set
|       CONFIG_ACPI_BUTTON=m
|       # CONFIG_ACPI_AC is not set
|       # CONFIG_ACPI_EC is not set
|       # CONFIG_APM is not set
|5. Downloaded and installed acpid-1.0.1-1.i386.rpm
|    Verified it's running and in a sleep state.
|6. Enabled every possible BIOS ACPI restore option.
|7. Looked at /proc directory, found there was a /proc/acpi
|    directory, but nothing related to acpi under /proc/sys
|    as the documentation (acpi_howto.txt) suggests.  As experience
|    has shown, documentation doesn't bare any resemblance to what
|    I'm seeing.
|8. Found /proc/acpi directory contains only "file" called events.
|9. Found there is no option in the kernel config file to turn on
|    or off Sleep mode.
|
|HELP!
