can you please recompile your kernel with INVARIANTS, DDB and KTR support?
Just add those lines:
and possibly remove kbdmux from your config file (not sure if it has
still problems with our syscons, though).
Then, when you hit that panic you should just be redirected to ddb.
At that point please write 'show ktr' in the ddb prompt and report
what it shows.
Thanks in advance,
