Hello Community!
I had the same problems written above; my machine did freeze at random
times after restart.
My configuration is :
ASUS P4C800 Deluxe Mainboard BIOS-Version: 1019.002 AMI-BIOS
Intel P4 2,6 GHz
1024 MB RAM
ATI 9700 PRO
160 GB Hitachi SATA-HDD as Bootmedium
USB Keyboard and USB Maus from Logitech
In various tests I established, that there is an relation between the
freezes and the Powermanagement-Settings:
BIOS:
APM enabled
ACPI 2.0 Support disabled
ACPI APIC Support enabled
BIOS -> AML ACPI Table enabled
Ubuntu 7.04 Alternate Installation -> there are freezes at random times.
There is no dependency on the used Graphics-Driver; by the way I had the
feeling that the accelerated Ati-Graphics-Driver is more stable.
BIOS:
APM enabled
ACPI 2.0 Support disabled
ACPI APIC Support enabled
BIOS -> AML ACPI Table enabled
Ubuntu:
Powernowd Service disabled
There are freezes at random times.
BIOS:
APM enabled
ACPI 2.0 Support disabled
ACPI APIC Support enabled
BIOS -> AML ACPI Table enabled
Ubuntu:
Powernowd Service disabled
Acpid Service disabled
Apmd Service disabled
It is impossible to work with the system; the machine freezes a few
minutes after every restart.
BIOS:
APM disabled
ACPI 2.0 Support disabled
ACPI APIC Support disabled
BIOS -> AML ACPI Table disabled
Ubuntu:
Powernowd Service disabled
Acpid Service disabled
Apmd Service disabled
Now only Grub is starting; Ubuntu doesnt start anylonger.
BIOS:
APM disabled
ACPI 2.0 Support disabled
ACPI APIC Support enabled
Bios -> AML ACPI Table enabled
Ubuntu:
Powernowd Service disabled
Acpid Service disabled
Apmd Service disabled
Ubuntu starts again, but freezes at random times.
BIOS:
APM disabled
ACPI 2.0 Support enabled
ACPI APIC Support enabled
BIOS -> AML ACPI Table enabled
Ubuntu:
ACPID Service disabled
APMD Service disabled
Powernowd Service disabled
Ubuntu is more stable and freezes after approximately 30 minutes.
BIOS:
APM disabled
ACPI 2.0 Support enabled
ACPI APIC Support enabled
BIOS -> AML ACPI Table enabled
Ubuntu:
ACPID Service enabled
APMD Service enabled
Powernowd Service disabled
Kernel changed from 2.6.20-16 (generic) to 2.6.20-16-386
Now my machine is running without freezes since 5 days with many
different progams and for many hours per day. I don't think that the
Kernel-Changing is the reason for the stability, because another user
(see also http://forum.ubuntuusers.de/topic/88548/180/) has an freeze
with Kernel 2.6.20-16-386 two days ago. So I think that the "right" APM
/ APIC Settings are the reason for the stability; but I have not the
knowledge what these settings mean. Perhaps there is an onther one who
can explain the settings and perhaps see the reason for the freezes.
I look forward that my comments will help to solve these bug. Please
apologize my bad English.
