CalDigit TS3+ dock station causes Kernel Panic (macOS 10.15.6)
This may not be applicable however the bundled support and drivers for the TS3+ available at https://downloads.caldigit.com/ contain a kext called CalDigitThunderboltStationChargingSupport.kext found under /Library/Extensions/
This seemed to be the root cause of all my issues once this was removed I was able to restart &amp; shutdown without issue for the past 4 weeks without issue.
the documented removal process can be found at https://archive.caldigit.com/KB/index.asp?KBID=142&amp;viewlocale=1
If you have installed this it may be the cause of your issues.
I have held off responding until I had a significant amount of time without the issue re-occouring before commenting.
