Public bug reported: I have a firewire audio device, M-Audio Firewire Solo. It works fine in Lucid but not so good in Marveric because of much FFADO XRUNs in jackd2.
My IEEE 1394 chipset is below, FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (rev 04) $ dpkg -l | grep ffado ii ffado-dbus-server 2.0.1+svn1856-1ubuntu1 FFADO D-Bus server ii ffado-mixer-qt4 2.0.1+svn1856-1ubuntu1 FFADO D-Bus mixer applets (QT4) ii ffado-tools 2.0.1+svn1856-1ubuntu1 FFADO debugging and firmware tools ii libffado2 2.0.1+svn1856-1ubuntu1 FFADO API At first, the kernel modules for this device is "New Firewire Stack" (so-called by FFADO developer), firewire_ohci, firewire_core and crc_itu_t. Then I get much FFADO XRuns, Secondly I use "Old Firewire Stack", ohci1394, raw1394, ieee1394 with the commands of rmmod and modprobe, these modules are standard in Lucid. Then I got a few FFADO XRUNs. In both ways, I play the same music in the same sequencer. In detail, please refer to the logs of "ffado-diag" and "jackd -v" I'LL attach. The "_old" means the old firewire stack and the "_new" means new one.
