Another question, probably not related to this. What about SMP? Do you have a multi core CPU? And do you also have instabilities, probably including kernel panics, if you run tasks which use both cores under heavy load like compiling the kernel from ABS or converting videos e.g. ripping a DVD with HandBrake or something like that, particularly when X is running at the same time?
