Not really. Acer laptops seem particularly bad. And, it turns out that
some chipsets have a way to disable SMM, which is used by RTAI, so maybe
this can be worked around. But, as the problem is broken hardware,
there will never be a real fix.
The best approach is probably to ask on this list whether anyone has
tried a particular laptop.

This doesn't really apply anymore, the kernel
bugs in question are
thought to be fixed. I run with ACPI enabled now and have not had a
problem in months.
I've been wondering about the 'acpi over smm' problems mentioned
on this list in Oct '04 for a while now - the problem doesn't seem to
get mentioned, yet I couldn't find a resolution in the list archives
(I could have missed it though).
(I mean the thread "Latency issues with laptops", at
http://music.columbia.edu/pipermail/linux-audio-user/2004-October/016545.ht… )
Does anyone know what the current state of play with this is?
Did the blacklist ever materialise, and is there any method of detecting
whether a particular laptop has the issue?
