Nope.  If I let installkernel make the new kernel the default kernel, I
don't even get to the boot menu.  Regardless of how I do it, new kernel
will start being loaded into memory (I will see a flash of the loading
info and twiddle) and then the computer will reboot instantly.

Something changed between October 12th and October 15th as a kernel from
the 12th is the last that will load and I first noticed the issue on the
15th (the next time I tried to compile a kernel).  Is there anything that
went into RELENG_5 during that period that could cause this?
