I'm porting an arm board from linux-3.10 to linux-3.12 and found that I can no longer detect the SD card. I found that the wait_for_completion(&mrq->completion) in drivers/mmc/core/core.c:mmc_wait_for_req_done() is never returning. I was able to bisect the problem to this commit: 0244ad004a54e39308d495fee0a2e637f8b5c317 is the first bad commit commit 0244ad004a54e39308d495fee0a2e637f8b5c317 Author: Martin Schwidefsky <schwidefsky@xxxxxxxxxx> Date: Fri Aug 30 09:39:53 2013 +0200 I'm not sure what I should do to fix the problem. Does anyone have any suggestions?
