I have applied the patch in bug 158160 to let coretemp recognize my Atom CPU.
This only impacts my home router but I have it applied to my source for this
NAS machine as well even though it is a no-op there. The relevant files
changed:
M share/man/man4/coretemp.4
M sys/dev/coretemp/coretemp.c
I realize the core dumps are rather useless now without the kernel.debug. I'm
learning as I go here. Let me know what else you may need.
