This seems to be a regression from commit 24d887436dcd5b6c18a7505e477c79cae3002c3a.
I'm not sure exactly why, but after running "reboot -r", init(8) does
something to trigger SIGSEGV, and the kernel appears to hang delivering
the signal in a loop.  In particular, init(8) registers a SIGSEGV
handler.

This breaks the EC2 builder images, which rely on reboot -r during boot,
but I can easily reproduce it in a VM.
