I suspect there is something we do when we read the sideband that makes the device router to "timeout" and retry the link establishment. There is also the failure when USB 3.x tunnel is created but we can look that after we figure out the connection issue. Looking at the trace we are still polling for retimers when we see the unplug: [ 48.684078] tb_tx Read Request Domain 0 Route 0 Adapter 3 / Lane 0x00/---- 0x00000000 0b00000000 00000000 00000000 00000000 ....

I compiled 6.12.0-rc5-00181-g6c52d4da1c74-dirty resulting in docking station not working.
Then I compiled 6.12.0-rc5-00181-g6c52d4da1c74-dirty without commit c6ca1ac9f472 (reverted), and now the docking station works correctly (as in screen output + USBs + Ethernet)
So it seems c6ca1ac9f472 is causing issues for my setup.
and see if that helps with the connection issue? If it does then can you take full dmesg and the trace again and with me so I can look at the USB tunnel issue too?
Below files are generated with commit c6ca1ac9f472 reverted! Tbtrace: https://gist.github.com/ricklahaye/05e54f12c974d3ed3e15527af7f67ed2 Dmesg: https://gist.github.com/ricklahaye/f50ad55159dec2b5265dd20bcebe4a10 Thank you, Kind regards, Rick Lahaye
