Title:
Raspberry Pi 3 network dies shortly after a burst of IPv6 tunnel
network load ((lan78xx): transmit queue 0 timed out)
Status in linux-raspi2 package in Ubuntu:
Incomplete
Status in linux-raspi2 source package in Eoan:
Won't Fix
Status in linux-raspi2 source package in Focal:
Confirmed
Bug description:
Desciption changed:
Raspberry Pi 3 network partially dies (transmission doesn't work, reception
still does) shortly after a burst of network load over IPv6, when IPv6
connectivity is provided by a tunnel from tunnelbroker.net. The triggering load
is typically an HTTP(S) download, and replication can be done without actually
saving the file (wget -O /dev/null ...). Problem happens within downloading ~10
GB, usually withinthe first 1 GB of traffic)
Replication is 100% as long as _all_ of the following conditions are met
- 6in4 tunnel to HE.net set up with netplan
- ipv6 rules applied (netfilter-persistent)
- ipv6 forwarding enabled (edit /etc/sysctl.conf)
