This one has happened without bge in kernel. I'm asking because I've seen several different scenarios of hangs and this is from one of them. I'll try to reproduce all cases and gather interrupt statistics from all of them. I'm wondering can't all this cases be caused by one common reason behind all of them. -- Oleg Sharoiko.
