The uploaded DSDT has the ACPI line which triggers the offending SMI
outcommented. This might lead to other side effects when (un-)plugging the AC,
so best only do it to verify the bug fixed or not. If it works now we need
input from Lenovo, they seem to have a bug in their BIOS SMM code then. (Maybe
an endless loop polling for AC state or something? That could explain why the
machine recovers after replugging the AC adapter again. Even there where no
interrupts for 5 seconds and even NMI watchdog kicked in between, but this is
pure guessing).
