You're out of vmalloc address space.  Each cx18 needs 64 MB of vmalloc
space for MMIO mappings.

Do this:

$ cat /proc/meminfo | grep Vmalloc

Edit your bootloader's config file to add a 'vmalloc=xxxM' option to
your kernel commandline.  Use a value that is 128M greater than your
current VmallocTotal.
