Unfortunately as the issue is intermittent, it is difficult to pinpoint a starting version exactly, but here's my best attempt:
Ubuntu zesty 4.10 series: definitely not affected Ubuntu artful 4.12 kernels: problem not observed, though other iwlwifi issues (bug 1719210) observed - probably not affected Ubuntu artful 4.13 kernels: 4.13.0-12.13 (current) definitely affected, unable to conclusively comment if earlier artful versions affected or not, due to already swapping kernels around a lot at the time troubleshooting the other mentioned bug. It's worth noting that there is a large change in the versions of the Intel iwlwifi firmware microcode loaded to the device between these mentioned kernel versions. Regrettably newer versions of the kernel have dropped support entirely for interacting with the known good microcode version, so it isn't possible to test changing the kernel and microcode versions independently. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722109 Title: iwlwifi regression in artful - intermittent total packet loss To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1722109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
