Delay messages in kernel.log

[trakuna]

Hello there, I have a problem with my newly installed Lion (10.7.3). Every now and then my system stops working for a couple of seconds and continues then as if nothing happened. The kernel.log is full of entries like

I am using the newest version of the chimera bootloader on an MSI P55-GD65 board with an i5 750. Maybe someone has an idea what could cause the lags? When this happens, I am still able to move the mouse around but the system does not react - even music and videos stop playing.

Okay, after reinstalling Lion and looking at the kernel logs after every step during my configuration i finally found the source of the messages. It's the driver for my Tascam US-144mkII audio interface. Too bad I still don't know how to fix it...
