Duron, 2.4.19, ACPI, APIC
Hallo!
Like many other people, I have problems running a newer kernel like the
2.4.19 on a machine with an AMD Duron 1300 and an ECS K7VMM mainboard.
While starting the kernel I get the message "ESR value before enabling
vector: 00000002" after that the system dies.
This happened with every Debian-kernel-type but the -386 one.
FInally I got the system running by compiling an own kernel with
completely NO APIC support and processor-type "Athlon" - that works.
But now I have the problem I can not take advantage of the ACPI
functionalities which may help me reducing my energy-expanses, as 122W
of continuous consume is a lot.
The "ospm-processor" driver starts, but it does not put the processor in
C2 state, as I can verify in "/proc/acpi/processor/0/status" ...
On the other hand I have an Amd Athlon 1200 (not XP-series) on an Abit
board running with Debian-kernel 2.4.19-k7 and loaded "ospm-processor"
module - and no problems.
Now, what exactly IS the problem?
What is the API-Controller used for, except for ACPI-support?
May it be an erranous ACPI-implementation of the BIOS (as described in
an article of the C'T magazine 25/2002)?
Or is it a different processor-architecture between the "Duron 1300" and
the "Athlon 1200" causing the problem?
If there were no practicable software-solution for that problem (ACPI
needed which needs APIC which collapses the kernel), I should change
some of the hardware-components - but what one?
Saluti!
Ludwig
