This is what I get right after boot and login into Unity 7 (executed in Gnome Terminal): $ ps aux | grep kworker | wc -l 1004
Kernel is 4.8.0-22-generic. After a few minutes, only 21 kworkers remain. Load after 4 minutes is not excessive (1244 sleeping processes), forgot to check load right after boot: up 4 min, 1 user, load average: 1,01, 1,79, 0,94 I'm not sure if it is of any help, but I've attached the output of "ps aux | grep kworker". ** Attachment added: "ps aux | grep kworker" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1626436/+attachment/4763631/+files/kworkers -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1626436 Title: [4.8 regression] boot has become very slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1626436/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
