https://bugzilla.kernel.org/show_bug.cgi?id=219198 --- Comment #13 from Markus Rathgeb (maggu2810@xxxxxxxxx) --- One additional information: I masked bolt.service (systemctl mask bolt.service) and restarted my system with dock disconnected. After the system is running (Wayland session) I looked at the kernel messages and connect the dock, disconnect the dock, connect the dock... The thunderbolt dock itself is detected but no peripheral. security is set to user $ cat /sys/bus/thunderbolt/devices/domain0/security user I created this udev rule "/etc/udev/rules.d/99-removable.rules" ACTION=="add", SUBSYSTEM=="thunderbolt", ATTR{authorized}=="0", ATTR{authorized}="1" Reload the rules and added the dock again. The attached USB keyboard has been detected. I disconnected the dock and reconnected it again. I see the DMAR error and no USB device is detect now. Just to replace bolt with a the simple udev rule and reduce the user space service(s) that are involved. -- You may reply to this email to add a comment.
