A kernel build 2. The scheduler_tick script (with a timeout of 5 seconds) in a loop (to simulate any issues with module loading/unloading) 3. The C module probing scheduler_tick() (attached to this bug) 4. The strace-open.stp example from the systemtap tutorial I haven't been able to see a problem or any fatal errors in the dmesg (except: ERROR: user string copy fault at 0x080c571a near identifier '$filename' at /usr/local/share/systemtap/tapset/syscalls2.stp:27:25 when running the strace-open.stp).
