OK, I tried that but I only find it's stuck in some keyboard interrupt
routine (presumably because I pressed ctrl-alt-esc).  If I type
"trace" or "where", I get the exact same answer no matter when I press
ctrl-alt-esc.  So what do I do?  Sorry if it's a dumb question.  The
FreeBSD developers handbook notes that trace may not be very useful
for this reason, but has no other suggestion.

No.  I'll try this with my next kernel build.

That was it, stupid of me.
