I'm unable to reproduce this issue. I have not fiddled with IPv6 yet due to my lack of knowledge and (IMO) unclear instructions in previous comments. I've pushed data through a wireguard tunnel while loading the Pi (because this sounds similar: https://github.com/raspberrypi/linux/issues/3782 but I've just realized, that that issue is filed against 3B and not 3B+, duh!). I've also tried the instructions from comment #43 but my test completes multiple times just fine.
I'm afraid there's not much I can do without *clear* instructions on how to reproduce this in an *isolated* environment using an *Ubuntu* image. ** Bug watch added: github.com/raspberrypi/linux/issues #3782 https://github.com/raspberrypi/linux/issues/3782 -- 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
