From the top off my head I have no explanation for that. You probably did not get it correct or I did not explain correctly: 1. just unloading ivtv before s2ram and re-loading after resume does not change things. 2. After PC was booted I can safely put it to S3 (s2ram) and it wakes up correctly with all but ivtv working. Power consumption is 8 watts less as before s2arm. 3. If I once performed step 2 (s2ram and wake up), I cannot put it to suspend a second time - it just does not terminate all processes. Just screen goes black, keyboard gets dead and power consumption does not change. Only a hard reset recovers the system (more or less ;-) I cannot tie this directly to ivtv, could also be some other issue with Ubuntu-Hardy. But to trace it down I first would like to sove the known ivtv problem. Seems that the card needs complete new initialisation including firmware upload.
