I rebuilt a kernel with /etc/mk.conf containing this:
SUDO=/usr/bin/sudo
DEBUG=-g
#DEBUGLIB=-g
But there are no line numbers in the ddb output (see end of dmesg). Is there
another why to build a kernel with debug symbols?

With a series of removals and insertions of the urtwn device I could
provoke another panic. I didn't wait for a timeout message to apear.
This time no nd6_* or in6_* are visible in the trace.
I updated kernel sources short before building the kernel.
