heh, I was wrong, it still happens but not always as it used to. I managed to reproduce the crash once today, and pressed alt+sysrq+1 and alt+sysrq+t to get a list of running tasks and their info. Hope it helps. I'll attach the kernel log which contains with a days worth of logs, and the tasks information towards the end.
