> I can confirm you that if you push the reset button on bottom of the
laptop with a needle (laptop unpowered, than use the power cord to start
it otherwhise will not start) the next boot all the ACPI events are logged
perfectly; all is run wanderfully untill some events that screw up again
the ACPI/BIOS stuff.

I can't track the cause of the corruption right now, but i suspect is
triggered by the suspend itself (maybe when is suspend overnight) i have to
test, but can confirm the trick can solve the problem untill it occur again
(sometimes after few ours, sometimes it last for 3/4 days).
