Re: NETDEV WATCHDOG: eth0 (lan78xx): transmit queue 0 timed out

Link to kernel bug report: https://github.com/raspberrypi/linux/issues/3401. If anyone wants to get this fixed, they're going to need more information - e.g. a way of reproducing it and/or much more detailed logs.

Re: NETDEV WATCHDOG: eth0 (lan78xx): transmit queue 0 timed out

I restart my router weekly "just in case". Every week when this happens I get this batch of errors on some, but no all, of my Pis.

I'm hoping it goes away someday, but in the meantime I just have to remember to check the timestamp to see if it's induced by the router reboot.

Re: NETDEV WATCHDOG: eth0 (lan78xx): transmit queue 0 timed out

Do we know which raspberry pi kernel version implemented the fix? Did it just get integrated in 5.10.17?

Re: NETDEV WATCHDOG: eth0 (lan78xx): transmit queue 0 timed out

... My (layman's) understanding is that late 2018, Linux introduced a performance optimisation, which doesn't play well with how lan78xx (and perhaps other drivers) use socket buffers. The fix goes into linux network code.
