"Bad trap" usually means that kernel tried something impossible. Usually it is dereferencing a bad pointer. It could be hardware, but my first guess would be a kernel bug, most likely in some driver. However, that "cmd: sched" makes me suspect the scheduler in this case. Really, I would call place a service call with Sun for something like this. If that is not possible, I would make sure that I have the last patch cluster for the os. Did you recently add some hardware to your box? If so, check for patches to the driver it uses. Also there is prtdiag -v which might yield some clues.
