Title:
Networking through Thunderbolt 3 Gen 2 stops working after a while
Status in linux package in Ubuntu:
Incomplete
Bug description:
After booting into 5.3.0-26 on my Lenovo X390, it has started to loose
network connection when connected to the Thunderbolt 3 Gen 2 dock
after a while. It varies how long it takes, but anywhere from quite
fast after boot to several hours of uptime. Suddenly no traffic goes
through the interface in the dock, but the device seems to be up.
Enabling wifi after it happens works fine, but unselecting "Enable
Networking" in network manager, or quitting it, makes the whole
computer hang (can move mouse, but no input from keyboard is
registered anymore, or so it seems at least)
Rebooting after it happens requires hard reset, as nothing happens
after Network Manager should stop.
Probably related to the patch introduces in LP: #1827961
