Eric, Sorry but the bug report can't be marked as Confirmed because only you incur in this issue (at the moment, at least).
Please provide: 1) dmesg without nohz=on kernel command-line parameter 2) output of "cyclictest -n -t3 -p99" with and without nohz=on (cyclictest is included into rt-tests package) FYI Dynanic Ticks are off by default since Hardy (included). Thanks! ** Changed in: linux-rt (Ubuntu) Status: Confirmed => New -- Performance really dropped with 2.6.31-8-rt https://bugs.launchpad.net/bugs/451169 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
