I agree, I have seen many warnings saying that can't load ACPI table, 
etc, etc, untill I put acpi=ht, and same errors are also on standar

It is a separate card, I will switch to a different slot, when I have 
some spare time, but this should not remove all warning/errors about 
ACPI, should it?

no idea how I could have disabled any flag to disable poweroff, any 
suggestion?
