AMD64 - kernel freezes when inserting processor/powernow-k8 module

AMD64 - kernel freezes when inserting processor/powernow-k8 module

[Thomas Renninger]

Hi,

the machine (AMD64 - 3200+) seems to have a terrible written DSDT.
After disassembling I could fix several small errors to get it compiled 
again.

Kernel 2.6.5-16 with latest ACPI patches ...

loading the powernow-k8 module freezes the machine immediately 
(POWERNOW-K8_ACPI compiled in and not compiled in)

loading the processor module freezes the machine also at once.
(could not get any info, even with acpi_debug function trace on, syslog 
buffering disabled).

Other ACPI related modules load and work fine (ac, battery, fan, of 
course not thermal as it depends on the processor mod).

You find the disassembled DSDT in: 
http://stio1.fh-wuerzburg.de/student/i31990/arima_hw_info/arima_dsdt.dsl

My modified (so that it compiles) DSDT is:
http://stio1.fh-wuerzburg.de/student/i31990/arima_hw_info/arima_dsdt_modif.dsl

and the acpidmp in:
http://stio1.fh-wuerzburg.de/student/i31990/arima_hw_info/acpidmp_arima_AMD64

If someone has a similar machine (AMD64 3200+), I would appreciate if 
you can send me your DSDT to compare it with mine.

Q: How can I access the Debug object/address used in ASL?

My experiences interpreting ASL code are limited..., please help...

Thanks.

      Thomas

Cheers, this prevents the machine to hang.
The hang is caused by some interference between the USB and firewire 
modules.
I recognised that the machine hangs when loading the processor module 
when the ehci_hcd or ohci1394 module has been loaded before.
Otherwise everything works fine...

Are there intentions to get this fixed, can I help/provide more info 
somehow?

If I load insmod ohci1394 and processor module is compiled-in, it
seems to work okay...

diff -u of a fix would be helpfull :-)))).

That's Arima, right? Is it production hw, btw?

I hate marketing numbers; is it 2GHz CPU? I have 2GHz Arima prototype here.
I got it to work okay, modulo internal speakers (headphones work)
and keyboard likes to loose clicks.

Strange, these work for me.

Ouch, you do know about neccesity of moving IO_PORT_BASE, right?

Ping me privately.
