The first trace is unusable (frames missing) and the second trace panics in sleep, which maybe points to the sound module and interrupts. Are you not able to panic the system without that sound module loaded? It looks too random to blame one module, more hardware, but it's possible the module exposes a bug elsewhere. From this though, it is hard to tell. -- Mel
