[FFADO-user] could not restart driver after freewheeling

[Tomasz G. <tgr...@gm...>]

Hello!

I use FFADO beta7, jack (svn) Rosegarden 1.7.2, Ardour 2.6.1 & several 
software synths.
My environment works fine besides one thing - when I export my audio 
session from Ardour, the whole wave file is saved correctly, but after 
that jack/ffado ALWAYS fail with the following error on the console:

libiec61883 warning: Established connection on channel 0.
You may need to manually set the channel on the receiving node.
libiec61883 warning: Established connection on channel 1.
You may need to manually set the channel on the transmitting node.
firewire ERR: Could not start streaming threads: -1
DRIVER NT: could not start driver
could not restart driver after freewheeling

and next I get tons of messages:
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
cannot read server event (Resource temporarily unavailable)
.
.
.

And during audio being exported from Ardour, qjactl displays some 
astronomous (>100%) CPU usage, and it stays like this until the failure 
described above comes.

Do you know what is wrong? Is it FFADO, JACK or Ardour's issue?
