I've also done the vmstat -i inspection briefly, all interrupt counters seem to be incrementing as normal. This problem may have cropped up after a set of suspend/resume sequences; right now I've had 3 warm reboots since yesterday (the laptop has been plugged in and unmoved), the problem has not yet manifested itself, but when I last noticed it, I had been suspending and resuming between leaving home and work. I realize this is purely anecdotal but I'll continue to observe for the problem re-emerging.
