I understand that this problem is still not fixed yet. It should be reopened:
# taskset -p $$ pid 2523's current affinity mask: ff # echo 0 > /sys/devices/system/cpu/cpu7/online # taskset -p $$ pid 12787's current affinity mask: 7f # echo 1 > /sys/devices/system/cpu/cpu7/online # cat /sys/devices/system/cpu/cpu7/online 1 # taskset -p $$ pid 12787's current affinity mask: 7f So, it seems that the mask doesn't get back to ff after the CPU is back online. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1392176 Title: mounts cgroups unconditionally which causes undesired effects with cpu hotplug To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cgmanager/+bug/1392176/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
