lol,  I don't feel addressed , nevertheless a few hints for the smartest of the smart (perhaps imp in this context).
It has to do with the SCSI-address of the card reader , since only cardreaders panic ,similar  like here :
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224037
Every other USB-plugged hardware(e.g HDD) I tested works …
Here`s the probe from generic-mmccam :
