Thanks...  I have version 1.41 of bcm2835_intr.c.  I noted that that the
panic occurs with evbarm6, evbarm7 and aarch64 on the RPI3.  I also
found that compiling a kernel with only single processor support
prevents the panic (disable MULTIPROCESSOR).  I won't be able to test
further for a couple of days, but I can try any suggestions anyone might
have when I become more available again.  Running SP is a little
annoying and probably not reasonable for the long term unless the
general thought is that the RPI3 is too long in the tooth to be well
supported.  I still suspect that there are a lot of them out there, but
that is mostly just my opinion.
