And I assume you never bothered to read the kernel messages which result
from this?  I guess this means I need to ensure that the kernel freezes
if you do this kind of thing so you can't ignore the complaints from
the L2C code.

It would be much better if you configured the L2C in the boot loader/
board firmware rather than trying to have the kernel do it.
