Well that's weird, it looks like you don't have any blocked tasks, so either
sysrq+w is screwing up or you are getting stuck in something CPU intensive.  Try
doing sysrq+w next time it happens again and also run top and see if something
is using up 100% of the CPU.  If it's something chewing up CPU then I'll tell
you how to figure out what's going on.  Thanks,
