Ok. I appended cma=64M to the end of the "append" line in
/boot/extlinux/extlinux.conf and rebooted the system. That had the
effect when I rebooted to cause my monitor to constantly flash on and
off repeatedly and would not let me get to the point of being able to
ssh into the system. Nor was I able to login via an alternate console.
I have since removed the cma=64M and rebooted to where I was without the
cma=64M appended.
Any other suggestions? They are most appreciated.
