The original issue from this thread was solved by this patch:
http://www.spinics.net/lists/arm-kernel/msg176093.html

For the mc13xxx hang, I started another thread:
http://marc.info/?l=linux-kernel&m=133778717002997&w=2

Please check the details there and any help is appreciatted.

Marc told us that he has no hardware to test mc13xxx via SPI.
