Public bug reported:

Suspending my computer with jackd running causes jackd to go into an
infinite loop when computer is resumed again. It consumes 100% of the
cpu and freezes the system for a short period, producing an endless
stream of the following messages:

firewire ERR: wait status < 0! (= -1)
JackAudioDriver::ProcessAsync: read error, skip cycle
JackFFADODriver::ffado_driver_wait - unhandled xrun
firewire ERR: wait status < 0! (= -1)
JackAudioDriver::ProcessAsync: read error, skip cycle
JackFFADODriver::ffado_driver_wait - unhandled xrun
firewire ERR: wait status < 0! (= -1)
JackAudioDriver::ProcessAsync: read error, skip cycle
JackFFADODriver::ffado_driver_wait - unhandled xrun

I'm using jackd2 (1.9.5~dfsg-19ubuntu1) and jackd2-firewire (1.9.5~dfsg-
19ubuntu1). My sound card is an Edirol FA-66.
