With 2.4.20 and acpi-20021212 patch, the system works with APIC disabled from BIOS! X-Windows and KDE is stable. My system was already stable in text-mode (run level 3).The errors which i obtained before are still there:- pci_bind-0191 [05] acpi_pci_bind : Device 00:00:04.00 not present in PCI namespace (Anyone know what the above means?!) and a series of AE_AML_BUFFER_LIMIT conditions. (Is there anyway to increase the 8 * (HOST BUFFER size) from 48 to 56?, and will that solve the problem?) It seems that the problem is when IO-APIC is used for IRQ routing. I greped /usr/src/linux*/drivers/acpi for AE_AML_BUFFER_LIMIT, and it seems (from dispatcher/dsopcode.c, line 496, in function Acpi_ds_init_buffer_field(...):- The Host buffer length, buffer_desc->buffer.length = 6, and if it was 7, it should work.(in my case) Is it possible to increase that buffer, something tells me it isn't as simple as :- buffer_desc->buffer.length = 7; :) Please understand that i know nothing about what i am talking about here, so anyone reading this should have a high stupidity tolerance! Please help if there is an easy fix to the above.
