Sorry about that, and thanks for the report - I think I know why that might be.

Can you post the output of dmesg | head -25?

Until there is a fix, you can revert to the previous version using:

sudo rpi-update 4f95c894c6a96b265d98f04a889e469833f7e996

I applied the patch successfully to my rpi. The cam works fine again.
