>How-To-Repeat:
Try installing 9.1 on device with RAM =<256MB. (?)
>Fix:
> This (i.e. the "kmem_map too small" message seen with kernel memory 
> shortage) could be due to CAM CTL ('device ctl' added in 9.1), which is 
> quite a big kernel memory consumer. 
> Try to disable CTL in loader with kern.cam.ctl.disable=1 to finish boot.
