I am having the same problem here.
It happened during make installworld of r314701. I run make installworld
while the former kernel r313407  was still active.
Now both kernels will boot up, but produce the same =22out of memory=22
message while going to single- or multi-user.
So it is not even possible to get a working shell in single-user mode.
As it first happens during make installworld while still running the
=22old=22 r313407 kernel I think the cause is not the kernel itself.
