: added for debugging to my kernelconfig:
: 
: options         KTR
: options         KTR_ENTRIES=1024
: options         KTR_VERBOSE
: options         KTR_ALQ

Actually you need the following:

#
# Compile with kernel debugger related code.
#
options 	KDB
#
# Enable the ddb debugger backend.
#
options 	DDB

and when the panic happens, you'll get 'db> ' prompt.  Type 'trace'
there and report what comes back.
