After an update to 5.3.0-26-generic (and then some time passed), got a connection fail when unsuspending.
The attached log is from journalctl -b -k with dyndbg enabled, from suspending (Jan 21, 23:58) through complete failure of the connection at 09:08:16 and a disconnect and reconnect that succeeded. ** Attachment added: "lp1856161-thunderbolt-debug.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+attachment/5322120/+files/lp1856161-thunderbolt-debug.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1856161 Title: Thunderbolt dock fails to connect USB devices To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1856161/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
