Hi, as reported in [1] in my post-scriptum I see several OOPs when running LTP and OOM tests (here: oom3). Linus requested to send you mm-folks my bug-report. # cd /opt/ltp/ # cat Version 20140115 # ./testcases/bin/oom03 I have tested with latest LTP (15-Jan-2014). If you need additional information, please let me know. Regards, - Sedat - P.S.: I made some testing w/ full-dynticks and basic-tick/simple-tick CPU accounting. The call-traces exist in both cases.
