solved. To fully initialize a debug session you must use the gdb command
"monitor reset halt". At one point the Eclipse IDE must have been generating
this (and other commands) automically and I must have deleted it or configure
my project somehow to mess it up...
(gdb) monitor reset halt

Update. With yet another alpha/releng install and build from the toplevel
Makefile produces a hsm.elf that runs as expected when flashed and run from
reset, but hangs at the same point during debug. For now I'm going to take this
clean copy and merge in my code using the burn and learn method of debug.

Wrong layer for me, you want Paul or Fredrik. :)
