I use a Thunderbolt Display through a TB2 -> 3 adaptor too and it’s an unreliable piece of crap. I haven’t had any panics from that (although plenty of unrelated panics), but I have to unplug it before I close the laptop, else it’s very unlikely to sleep. Despite not having any external peripherals connected, it always goes into clamshell mode rather than sleep. It then appears to sleep (i.e. the display goes off), but then I come back to my desk the next morning to find the laptop uncomfortably warm with the fans running, while closed and doing literally nothing. The more I spend on MacBooks the more issues they seem to have.
