Actually, since ACPI does explicitely require that interrupts
are off at some point during state transitions, basically
all code reachable by the AML interpreter must be safe to
be run without interrupts.

Btw, it might also make sense to avoid tsleep et al
while DDB is active. A context switch while the other CPU
is in the DDB loop doesn't lead to anything.

Matthias
