Last cvsup was early Nov, shortly after 4.9 was released... guess
it is time for a refresh.

To load modules
kldload cxm_iic
kldload cxm

to unload
kldunload cxm
kldunload cxm_iic

I have cvsuped stable and rebuilt with your latest drivers (Jan 25),
I will let you know if this behaves better (so far so good).
