I have the same symptoms with 4.10.0-041000rc3-generic . I've attaches a copy of syslog which records the system booting with the Thunderbolt attached, then being removed and re-inserted.
Search for the annotations in the syslog file: syslog_boot_with_thunderbolt_then_reseat: "Removing Thunderbolt" "Replacing Thunderbolt" "Done with Thunderbolt" duncan@relapse:~$ uname -a Linux relapse 4.10.0-041000rc3-generic #201701081831 SMP Sun Jan 8 23:33:02 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ** Attachment added: "syslog_boot_with_thunderbolt_then_reseat" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1654214/+attachment/4802783/+files/syslog_boot_with_thunderbolt_then_reseat -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654214 Title: Belkin Thunderbolt 2 Express Dock HD display port hot plug not supported.
