I'm not entirely sure what this tells me, but IRQ usage drops significantly (particularly on "LOC") when not playing back a video. Maybe somebody smarter than I am has a though. The poorly drawn yellow line is roughly when i stopped any video play back in this graph. Time scale is a 15 minute window from collectd's irq monitor. [image: Inline image 1]
