Comment 3 for bug 586209

I'm getting the same thing on Natty. Here's the message I get from qjackctl's messages pannel:

ALSA: poll time out, polled for 4353014 usecs
DRIVER NT: could not run driver cycle
21:37:56.930 JACK connection graph change.
jack main caught signal 12
no message buffer overruns
cannot read server event (Success)
cannot continue execution of the processing graph (Bad file descriptor)

The last line repeats about 100 times.
