ffado and jack keep freezing - I need your help

         Hi, everyone. I'm here to get some
            troubleshooting from you.

          
            I installed ffado and jack on Archlinux, but I can't get it
            working properly.

            
            About my system:

            
            - Thinkpad x201i(Intel i3-380m and 8G memory)

            
            - Echo Audiofire2 (connected via expresscard)

            
            - Archlinux 64bit

            
            - 2.6.39 kernel (BFS patched)

            
            - installed libffado 2.0.1-3 (svn version from aur) and jack
            1.9.5-1

            
            - configured to the advice from the script
            realtimeconfigquickscan(except the realtime kernel and
            1000hz clock part)

            
            - running rtirq daemon. configured as below....

            
            RTIRQ_NAME_LIST="rtc firewire_ohci ehci_hcd:usb1
            ehci_hcd:usb2 i8042"

            
            RTIRQ_NON_THREADED="rtc"

            
           Symtoms:

            
            - ffado and jack work for some time(about 30 seconds?) then
            freeze.

            
            detailed process...

            
            Arch starts

            turn qjackctl on

            start other audio apps (tested with hydrogen and qsynth)

            Seems working well

            After some time, all sounds stop and transport doesn't roll

            When I close other apps and press stop button on qjackctl,
            it displays 'stopping...' and nothing more. here's jacks
            messages after the stop button pressed.

          ... and no more. it just holds here.

        
        - But ffado and jack work just
            nicely not freezing in extremely rare cases (with no xruns)

          
          I wanted to check messages from ffado too, but I don't know
          how.

          
          Can anyone give me a likely solution to this problem? Or any
          more information needed?

        
          Thanks in advance!
