Hi,
On next-20130628 I get the following Oops during reboot:
[ 89.814921] Unable to handle kernel NULL pointer dereference at virtual address 0000004c
[ 89.824208] pgd = ecd54000
[ 89.827276] [0000004c] *pgd=00000000

The corresponding line in mmc_bus_shutdown is "drv->shutdown(card);"
and 'drv' seems indeed to be NULL.
