Same thing here... 20190709 (4.19.57) kernel has broken LAN (on Pi 3B and 3B+ boards), rolling back to 4.19.42 cures the problem. With .57 kernel I saw lots of messages from the lan78xx module about failures to read data.

@kpfleming Are you able to provide some dmesg output?

[kpfleming]

Not directly, as the system fails to boot all the way to userspace. I can capture serial console output, but unfortunately not in the next week as I'll be away from the location of the RPis.

Hi,

This issue is not there with kernel version 4.14.98, if you are still not facing this issue, can this issue be closed.

Regards,
Sudhamani.
