Public bug reported: I have a problem similar to the bug #1599476, my system freezes when I unplug my thunderbolt port if it is connected during startup.
What I have tested so far : * If the thunderbolt is plugged at startup and I unplug it -> System freeze * If the thunderbolt is not plugged at startup, I can plug it and unplug it fine. What I expect to happen : Being able to unplug my thunderbolt without the system freezing. I updated my BIOS and the firmware of the dock : 13:47 troche@serenity ~ % sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 1.2.19 12/22/2016 This was working fine in Ubuntu 16.04, and it is not working since my update to Ubuntu 16.10. 13:47 troche@serenity ~ % lsb_release -rd Description: Ubuntu 16.10 Release: 16.10 My computer is a Dell Precision 5510 laptop with a dock WD15 Thunderbolt.
