I live with this bug for more than a year and I do not know any kernel version where this bug did not occur.
As the bug only occur from time to time I checked how often it trigger with the normal ubuntu kernel. During 20 restarts the bug was triggered 3 times. After installing kernel 4.2.0-040200.201508301530 I restarted my server again 20 times and the bug occur 2 times. As a side note when the bug occur the network indicator need multiple seconds longer to show up after bootup in the notification area. ** Tags added: kernel-bug-exists-upstream ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492824 Title: Intel NIC ignore sometimes all received messages To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492824/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
