I caught two instances of the above BUG() in rmque() after [decoded oopses attached]. The kernel is 2.4.17, untainted but with a few patches (low-latency, o1, elevator, lkcd). I've got a full kernel crash dump from the second instance in case it is needed. I'm currently running 2.4.18 and just the lkcd patch in order to see if the problem recurs. MikaL
