I belive the poll in question is: (gdb) where #0 0x00007f74414c2d40 in poll () from /lib/x86_64-linux-gnu/libc.so.6 #1 0x00007f7441a08136 in ??

I see a poll with a zero timeout, followed by a failed read on an eventfd and then a 100ms poll with a timeout: poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=9, events=POLLIN}, {fd=7, events=POLLIN}], 6, 0) = 0 (Timeout) read(4, 0x7fffd02fb220, 16) = -1 EAGAIN (Resource temporarily unavailable) recvfrom(3, 0x15f1ef4, 4096, 0, 0, 0) = -1 EAGAIN (Resource temporarily unavailable) poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=9, events=POLLIN}, {fd=7, events=POLLIN}], 6, 100) = 0 (Timeout) The fd's are as follow: lr-x------ 1 king king 64 Feb 27 09:04 0 -> /dev/null l-wx------ 1 king king 64 Feb 27 09:04 1 -> /home/king/.xsession-errors lrwx------ 1 king king 64 Feb 27 09:04 10 -> anon_inode:[eventfd] lrwx------ 1 king king 64 Feb 27 09:04 11 -> anon_inode:[eventfd] l-wx------ 1 king king 64 Feb 27 09:04 2 -> /home/king/.xsession-errors lrwx------ 1 king king 64 Feb 27 09:04 3 -> socket:[13455] lr-x------ 1 king king 64 Feb 27 09:04 4 -> anon_inode:[eventfd] l-wx------ 1 king king 64 Feb 27 09:04 5 -> socket:[13460] l-wx------ 1 king king 64 Feb 27 09:04 6 -> socket:[13249] lrwx------ 1 king king 64 Feb 27 09:04 7 -> socket:[13251] lrwx------ 1 king king 64 Feb 27 09:04 8 -> socket:[13592] lrwx------ 1 king king 64 Feb 27 09:04 9 -> socket:[13600] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/934117 Title: nm-applet is calling poll() at ~10Hz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-consumption/+bug/934117/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
