ccd error with two large components

[Paul Goyette <paul%whooppee.com@localhost>]

I have two 2TB nvme devices, configured with ``ccdconfig ccd0 64 
none /dev/dk1 /dev/dk0''
then i mount the ccd on /mnt
and then ccdconfig -g goes boom!!

	prevented access to 0x7f7fff9e7fbc (SMAP)
	ccd_info_sysctl+77

The instruction decode at that point is

	movl 0(%r8), %esi

(The rest of the backtrace isn't very interesting, just the
sysctl dispatch.)

Any clues?
