The errors in the kernel log don't appear with kernel version 4.10.17. However, I still get lockups with that kernel as well.
At this point I think the lockups are probably not related to the warnings and are possibly caused by a hardware failure. The errors in the log are still a valid issue, IMHO. ** Summary changed: - tcp_fastretrans_alert kernel warnings, possible system hardlock + tcp_fastretrans_alert kernel warnings -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1744379 Title: tcp_fastretrans_alert kernel warnings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1744379/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
