I will take a look at your logs today but in the meantime can you run following command on the system with the dock connected? # tbdump -r 0 -a 1 -vv -N 2 LANE_ADP_CS_0 Here tbdump comes from https://github.com/intel/tbtools. It should be pretty straighforward to build but let me know if any issues (unfortunately there is no binary package available at this time). The '-a 1' should match the adapter the dock is connected. You can get it for instance like this (this is an example from my system): # tblist Domain 0 Route 0: 8087:7eb2 Intel Gen14 Domain 0 Route 1: 003d:0011 CalDigit, Inc. TS3 Plus Domain 1 Route 0: 8087:7eb2 Intel Gen14 Here the CalDigit has "Route 1" so it means I use "-a 1" above. It could be also "Domain 0 Route 3" in which case replace the "-a 1" with "-a 3". This command should dump two lane adapter registers LANE_ADP_CS_0/1 that show the link capabilities.
