Thanks very much for doing that, sorry it didn't help. There's another related patch for your controller: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/773524 This was merged as 15bed0f2fa8e1d7db ("mmc: Added quirks for Ricoh 1180:e823 lower base clock frequency"). Perhaps you could check that this code is running for you? If it is running, and not helping, can I persuade you to try a full bisection? I don't think we have other reports of this bug, and the only other person who has reported something like it wasn't a kernel hacker.
