Hmm.  I can't find that string anywhere in the sources.  Are you sure
"rm.mutex_mtx" is correct?

Should be just "ps".  There's no point in this case because the system
panic'd before it finished booting.  Instead, run "trace" and post the
results.

I suggest you read ddb(4) and the developer's handbook URL that I posted.

One option in this case is to take a photo and put it up on the web
