debugging boltd and Dell TB16 on Dell Latitude 5491 and Xubuntu 18.04

0

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.

  • OS: Xubuntu 18.04.2 LTS
  • Kernel: 4.15.0-54-generic #58
  • System: Dell Latitude 5491 BIOS 1.8.1 05/23/2019

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.
