hello all.
trying to kompile the 2.6.1. kernel on my presario 2100.
the compilation goes ok, but when i restart my machine it hangs when it gets to:

ACPI: Subsystem revision 20031002

i tried to compile acpi as modules, but the i get:

ACPI: Subsystem revision 20031002
Spurious 8259A interrupt:IRQ7

Anyone have an idea what`s wrong? do i need to add some more to the kernel?

regards

Umm... I'm going out on a limb here but check your bios and see if there are any ACPI settings to play around with in there and also you might want to check the APIC setup in the kernel and yes APIC is differen't then ACPI. I believe lilo.conf will mention something about the APIC that you can enable or disable.

ok, now i`ve tried to compile both with and without apic. looked in my bios, nothing is mentioned there about acpi. when i tried with the apic i got:
ACPI: IRQ9 SCI: Level Trigger

no idea what it means.

generally, just enable SMP support , and enable acpi support (building everything else in acpi as a module would be good).
also might want to make sure you dont have any apm service running.

CONFIG_PM=y
CONFIG_ACPI_BOOT=y

are pretty ,much all you need (along with the acpi and acpid packages.)

thanks very much, i`ll get to compiling right away.

Try adding force noapic in your addendum line in lilo and see if that helps. There is a known conflict between APIC and ACPI, and adding the 'force noapic' tends to cure it.

did it work?

dont think that apic and acpi conflict, but i dunno.

Thought that good implementations of acpi depend on apic for interrupts n stuff, but like i said, i dunno

my machine does wierd things (2.6.4, alsa, acpi--initrd patch but A15 M50 BIOS) when that error is appended to dmesg...

with xircom parent inserted (but not in use) and 3com Vortex/Boomerang working (usually in X), the network goes down and cant be restarted without a reboot, oh yeah, apic not configured in kernel--not a problem in 2.4.X kernels configured because it said that apic could not be found or something but something like "dummy apic being used instead"

sorry for the late reply.
tried the force noapic command, but it didnt work.
are basically lost in this matter...
