Multiple Maudio 2496

Hi, I am using two Maudio 2496 as Multiple Multiple sound cards described on this Website: http://www.sound-man.co.uk/linuxaudio/ice1712multi.html With 64studio 2.1 with the 2.6.21kernel it works perfect, the same works on the beta3 with 2.6.21 kernel. but with the 2.6.26 and the 2.6.29-1 it will not work, the terminal output is this: JackAudioDriver:: Process Async: read error, skip cycle is there a possibility to synchronize the two cards, or is it because of the kernels and if so will it be solved in the final release of 3.0. Greetings, Thomas
