A couple of things about ACPI

A couple of things about ACPI

[David Carlos Manuelda]

[-- Attachment #1: Type: text/plain, Size: 1400 bytes --]

I've seen in dmesg some things I wanted to comment to you.

First of all, I've seen a message at boot:

ACPI: System BIOS is requesting _OSI(Linux)
ACPI: Please test with "acpi_osi=!Linux"
Please send dmidecode to linux-acpi@vger.kernel.org

I've tested with that boot option, and I see exactly same message (maybe a 
bug?)

dmidecode is attached.
=========================
I've seen:
ACPI: BIOS bug: multiple APIC/MADT found, using 0
ACPI: If "acpi_apic_instance=2" works better, notify 
linux-acpi@vger.kernel.org
Testing with that option, I see no difference, except the message change, now 
says:
ACPI: BIOS bug: multiple APIC/MADT found, using 2
ACPI: If "acpi_apic_instance=0" works better, notify 
linux-acpi@vger.kernel.org
=========================
I don't know what it is exactly, but I mail you with information requested.

Please let me know if it is useful, and if you need more info, just tell me.

This is a Samsung R70 laptop, intel core2 duo 1800, 2GB ram 'Santa Rosa'.

By the way, info of dmidecode is not 100% correct, I don't know why. This is 
what is not correct:

extract of dmidecode.txt:
====================
Handle 0x000B, DMI type 10, 6 bytes
On Board Device Information
        Type: Sound
        Status: Disabled (***!!! Sound is enabled and fully functional)
        Description: HD-Audio
=======
I wait for your answer, hope this is useful to improve kernel.

David.

thanks, i'll look at this.
i also need to simplify it so that it just prints out the dmi into
right in the dmesg instead of asking for dmidecode....

we can tell exactly what this does if you open up a bug report
and attach the output from acpidump.
So far, i've seen OSI(Linux) used only for video re-post on resume.

again, the acpidump will tell us the two table contents and we can compare.
when they are very broken, usually an IRQ is mis-routed (could tell from
both /proc/interrupts) or not all the processors are enumerated.

DMI info is generally typed in by hand, and it is common for it
to be full of errors.
