Comment 1 Ingo Molnar 2007-11-17 18:31:44 UTC
Please check whether this occurs with 2.6.24-rc3 or later kernels - we fixed a particular SMP race that could explain this crash.
Comment 2 Ingo Molnar 2007-11-20 00:29:50 UTC
reports of this bug have disappeared for now - it should be fixed by this commit:

    sched: fix __set_task_cpu() SMP race
    
    Grant Wilson has reported rare SCHED_FAIR_USER crashes on his quad-core
    system, which crashes can only be explained via runqueue corruption.
<--------------------------

please reopen the bug if it still triggers for you.
