Mathias, the problem that you're having is not exactly the same as the one I had, I don't think, but I've had a similar problem: it looks like you're using an SMP kernel, which, I have noticed sometimes hangs because of IRQ timing issues. I'm not quite sure what causes this, but the consensus seems to be that it has something to do with CPU time scaling. Sometimes these lockups happen after you change your CPU time scaling scheme using a power manager app (for example from Ondemand to Performance). Try disabling time scaling and see if the problem persists. Also, if you are running any application that affects IRQ timing, such as irqbalance, try disabling it. I had a similar problem and it appears to have gone away after I disabled irqbalance.
