Hi,

Just "acpi=off" works here.
Indeed, this i can confirm. With acpi=off, the laptop suspend (or
hybernate?) works again. Of course, there is no "acpi", and thus some
other features become missing, for example, the CPU speed of the T40
laptop gets stuck at 600MHz, and does not change depending on the
presence of the AC input.
I will try the stuff from
http://www.suspend2.net.
