Assuming it is over DisplayPort tunnel, at that point the device router is already enumerated. This patch just speeds up the enumeration to cope with the Pluggable device internal timeout. Please attach full dmesg with "thunderbolt.dyndbg=+p" in the command line too to that new issue. -- You may reply to this email to add a comment.
