It dropped down to the SRM with the RA at XentMM (../../alpha/alpha/exception.s:88) about 1/2 way through a buildworld (no -j's). I had to steal the console by killing the kermit I had running in the office, so I have no idea what message were emitted. I suspect it was another ksp not valid halt. Which means that it is still faulting in the fault path and recursing until it exhausts the stack space. This is a UP kernel. As luck would have it, I have an assert in my trap.c to catch this sort of thing, but it uses kernnest & is dependent on SMP. D'oh!
