My Laptop (HP Elitebook 8560p) started throw
" mmc0: Timeout waiting for hardware interrupt." at updating from
3.3-rc7 to 3.4-rc1 and is no longer able to mount my SD-card.

I bisected this and found the culprit to be:
e6039832bed9a9b967796d7021f17f25b625b616 is the first bad commit
commit e6039832bed9a9b967796d7021f17f25b625b616
