Comment 5 for bug 398109

Hey all...

I was a little busy last time, but I found solution ;)

I've got Asus M2N-MX SE Plus mainboard.
Usermanual you can find here:
http://support.asus.com/download/download.aspx?SLanguage=en-us&model=M2N-MX%20SE%20Plus
BIOS version is v02.58 1958-2007 American Megartends inc.
Kernel is 2.6.28-14.47

1) Default BIOS settings :
* Cool'n'Qulet - disabled
* ACPI APIC support - enabled
* MCP61 ACPI HPET TABLE - enabled
Error is: MP-BIOS bug: 8254 timer not connected to IO-APIC
Log file is: dmesg1

2) Settings A:
+ Cool'n'Qulet - enabled (changed)
* ACPI APIC support - enabled
* MCP61 ACPI HPET TABLE - enabled
Error is: MP-BIOS bug: 8254 timer not connected to IO-APIC
Log file is: dmesg2

3) Settings B:
+ Cool'n'Qulet - enabled (changed)
+ ACPI APIC support - disabled (changed)
* MCP61 ACPI HPET TABLE - enabled
Error is: [Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor.
Log file is: dmesg3

3) Settings B:
+ Cool'n'Qulet - enabled (changed)
* ACPI APIC support - enabled (default)
+ MCP61 ACPI HPET TABLE - disabled (changed)
No errors!!!
Log file is: dmesg4

So, that you can see the reason was in MCP61 ACPI HPET TABLE setting.
Have anybody got some ideas about this situation?
