Every now and then my Dell TB16 dock device stops working i.e. port replication is off, also the dock's white LED goes off.
I've installed the thunderbolt daemon boltd
but the boltctl
command produces no output. In dmesg I can't see neither data.
In the /var/log/syslog though I can see repeated initialization and shutdown cycles of the thunderbolt device.
