With release kernels stack trace appears with this
message, then it sits in ddb, forget how to print panic?

panic: access but not attached


With snapshots, both panic and stacktrace print
but it doesn't ddb and goes straight to reboot. I forget
how to make those enter ddb or 15sec countdown?

In interim..
fatal trap 12 page fault while in kernel mode
supervosor read data page not present
process = mount


I did file a ticket with script so anyone with a blank
usb stick can recreate locally.
