Some how, my changes to gcc in r247012 is causing this, even when using
the default of clang as cc... I was able to reproduce a crash myself,
and then I just backed my change and the new kernel booted...
I'm about to do a binary diff between the broken kernel and the new
kernel (since I only installed the kernel, not userland) and figure
out which part of the system.. But clearly, we are still using gcc
somehow in our kernel builds...
If I don't figure out what it is in a few hours, I'll back out the
