Re: ACPI source release updated (20021002)

[Bernd Pfrommer <berndp-p32f3XyCuykqcZcGjlUOXw@public.gmane.org>]

Replaced DSDT, but alas, this still did not fix the problem (I had tried 
that with an earlier version of ACPI, and it didn't help there either).
Some more questions:
    - it seems that there are a lot of these link devices, not just 
LNUS, no? Or do you think LNUS is the only one causing trouble? Maybe I 
can somehow get rid of it then?
    - is there a way to disable the link devices altogether by modifying 
the DSDT?
    - any suggestions as to why pci=noacpi does not fix the problem?
    - any other things I could try?

Thanks,
Bernd
