This is printed by https://nxr.netbsd.org/xref/src/sbin/init/init.c#486

Bummer you don't see the signal number.

I would set a breakpoint in DDB on `kpsignal2' or `sigpost' or add a printf
to those functions in sys/kern/kern_sig.c and print the signal number.

I would also check whether init(8) is running on the boot (primary) CPU or
on one of the others.  If it is not running on the boot CPU I would suspect
cache synchronization issues similar to what I ran into with
