Re: interrupt at 50% on dell E5450

I'm back with some interesting info :-).

By disabling each acpi module, I've discovered that the problem disappeared
when I disable "acpiprt" in UKC.

Based on the manpage, this module maps the PCI ...

So, I've disabled each PCI.

interrupts are gone when I disable "ichiic" in UKC :-) .

(When I do not disable it it link to iic and then to spdmem0 (cfr dmesg in
my previous email))


After such desabling, the rest of the machine seams to work. But I have to
check ii more deeply.
At least "Top" says that my 8GB memory are still present


note: my laptop speaker is still making small noise when not muted.


Questions:
What is this modeule "ichiic" ? What am I missing by disabling it ?
Why this module create interruputs on this Dell machine (e5450) ?
Is there a link with the speaker ?
