Thank you for replying :-).

I'm indeed not using APIC (ISTR it was designed for SMP, I don't know
what benefit I could get from it considering my laptop is UP).

I stopped using ACPI a few months ago as it prevented psm(4) from
working (albeit it ACPI+SMP doesn't exhibit the problem) (see [1]).

What do you advice me to do?  Do you need me to do some testing,
enabling ACPI or something like that?  I'm at work currently, I will
only be able to do this in a couple of hour.

Regards,
