Hi all
I realise this is not the place to ask such a question but rather than
subscribing to yet another forum I ask first just in case.
I have demudi working now, all except it turning the machine off. It
goes to shut down the last line on the screen is Power Down but then it
just sits there. I have to physically turn it off.
any ideas?
I'm experiencing the exact same thing with Mandrake's "multimedia"
kernels. I haven't been bothered enough by it to try and fix it, but if
you find an easy fix, please let me know. =)

This works for me but I know that it didn't for some others. Hmm.. now
that I know that it could cost some latency ms, I might not use that
anymore...
I believe the big ACPI latency bug was fixed in 2.6.10. So that kernel
should not be affected.
Of course if your hardware has a buggy ACPI implementation you will have
latency problems regardless of the OS or kernel you use, and whether
ACPI is enabled. This is a separate issue.
It looks like Acer laptops are particularly bad, they all seem to suffer
from the ACPI/SMM issue.

Yes, I confirm this unfortunately. I have an Acer laptop (not the one
with Demudi on it). Every bit of hardware runs fine, except ACPI.
(Kernel 2.6.6 - would a newer version help?)

Same with me, I fixed the problem by adding
append="acpi=force"
to the Demudi-section of my /etc/lilo.conf.
Before this, the kernel refused to automatically use ACPI because the
BIOS was older than some specific date, although it has nominal ACPI
support (I remember a log message like: "ACPI disabled by default
because your BIOS is too old").
It's Demudi 1.2.0 and the default 2.4 kernel with its mm-patches.
