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.
Thanks!
- Chris.
