With the following sequence: kvm__pause(); kvm__continue(); kvm__pause(); There is a chance that not all paused threads have been resumed, and the second kvm__pause will attempt to pause them again. Since the paused thread is waiting to own the pause_lock, it won't write its second pause notification. kvm__pause will be waiting for that notification while owning pause_lock, so... deadlock. Simple solution is not to try to pause thread that had not the chance to resume. Signed-off-by: Julien Thierry <julien.thierry@arm.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
