Title:
Lost network connection, seems like an older kernel bug
Status in linux package in Ubuntu:
Expired
Bug description:
I experience what seems the exact copy of the issue here after I have
connected my Dell laptop to a Dell Monitor with an embedded Ethernet over
USB-C/Thunderbolt (and USB-B High Speed Upstream Cable). Suddenly no network
connection and it can not be restored for a long time or until reboot.
