@mlx -- dunno. What I do know is reverting to prior firmware solves the issue for me and at least @Tim.
I had the same issue in May as there was another release. I reverted and it became stable. This summer, I tried to sudo apt upgrade and hit the problem again. So I reverted and am stable. Would like to get back to the tip for sure, but instability is instability. And it seems it's a shared problem across ETH0 and WLAN1 based on this thread. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1861936 Title: Raspberry Pi 3 network dies shortly after a burst of IPv6 tunnel network load ((lan78xx): transmit queue 0 timed out) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1861936/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
