Not sure if this helps, but I read this in the controller release notes:

CSCsd52483?When you make changes in the bootloader of a 2006 controller or a Controller Network Module, the bootup process may halt, and the controller may stop responding. The controller also displays the "grub>" prompt on the console port.

Workaround: Replace the controller.

Yes, i saw the same thing, and i called to cisco and they are going to replace mi WLC.

Thank you

I had the same issue, but found different solution. In my case, CF card inside 2106 came loose. In order to re-insert it, top cover has to be removed. It is fairly easy with 3 screws on the bottom of the unit.
