boot broken on VMWare somewhere between r300069 and r300176

I did an IFC on my drm-next-4.6 branch yesterday at r300069. I just
did an IFC to r300176 and boot will hang right ater printing out
"setting hostid: ". ^T just shows sh [piperd]. ddb just shows the
shell as hanging in piperead. Diffing between those two revisions I
don't see any obvious offenders so I'm hoping that individuals who
have committed in the last 24 hours will have some idea of their
changes having such an impact.

Thanks in advance.
