Could you give me some instructions? I use Debian, so I just tried find / -exec dd if='{}' of=/dev/null bs00 count 0 \; This should generate some heavy disk load, shouldn't it? I also tried starting two such processes in parallel, but I did not experience any crashes so far. Maybe this is of some importance: I use the deadline scheduler.
