Then I restarted the video and did a couple more suspend cycles to see if it would not continue again. In the subsequent tries it would resume fine and the video would continue playing too. So I'm going to chalk that single case of halted video with the second patch to a resume glitch or so. Btw, I don't have pm-suspend on that box but I did suspend to RAM assuming this is what you wanted, which is done as root with two commands: # echo "suspend" > /sys/power/disk # echo "mem" > /sys/power/state If you want me to do more extensive testing, just shoot.
