RE: K7 CPU disconnect & system lock

["Thomas Herrmann" <ollo.diab-Mmb7MZpHnFY@public.gmane.org>]

[-- Attachment #1: Type: text/plain, Size: 2254 bytes --]

Hi Len,

the K7 cpu disconnect feature is a power save mode, where the CPU
disconnects from the north bridge and goes into sleep mode. Any interrupt will wake-up
the CPU which then needs to connect to the north bridge again to transfer
data. While CPU disconnect enabled the idle temperature of the CPU drops from
around 52C to 27C on my systems. On certain systems this feature can be enabled
via BIOS, but there is also a tool called "athcool" which sets the
configuration register.

I have attached the requested logs. As you will see while acpi=off certain
devices (like USB) are not available due to no IRQ routing. All devices work
fine with acpi enabled.

Regards,   Thomas
