There are few things that can help: 1) applying the cycle skip patch to the 1394 kernel sources: http://subversion.ffado.org/wiki/TxSkipPatched 2) decreasing the amount of kernel space buffering will result in this being less likely to occur. You can specify a config file: http://subversion.ffado.org/wiki/ConfigFile Setting the max_nb_buffers_xmit to 32 (or lower) should help. Note however that this will result in a higher sensitivity to xruns since this means that userspace has to refill the buffers every 32/2*8 frames. Probably the best solution is to get a better host controller.
