>Description:
I did a "make world' today. 
I use a bluetooth dongle. 

First I load ng_ubt : kldload ng_ubt
# kldload ng_ubt

Then I plug the dongle (below extract from all.log):

I use a non USB keyboard which gets superseded by a virtual bluetooth one (I guess).
Removing the USB dongle at this point causes a kernel panic.
>How-To-Repeat:
Ugrade the system and kernel to 18.09.04 then use a bluetooth dongle...
