It appears that this patch appears to enable the card reader, it fails to mount/use/unmount MMC cards successfully. We are seeing failures on two Toshiba R850 (Intel and AMD) laptops with the 11.04 release of Natty.

The output from lspci is:
 * System peripheral: Ricoh Co Ltd Device e823 (rev 04)

It appears to be a known issue according to:

 * http://groups.google.com/group/linux.kernel/browse_thread/thread/81d5997647563887?pli=1

And it doesn't appear others have reported successfully using MMC.

-- cut and paste from the URL above --

Okay. There's nothing in the log about Ricoh, which probably means that
it bailed out early in the function. You could add a printk to the top
of ricoh_mmc_fixup_rl5c476() if you want to be really sure that the code
there is getting a chance to run.

I think the likely conclusion is that:

(a) The Ricoh controller has a proprietary MMC function that is stealing
    MMC cards away from the SDHCI controller even though the SDHCI could
    read them if it had a chance to.

(b) We don't know how to turn the MMC controller off, because our old
    method for doing so isn't working on this new 0xe823 model.

I'm adding a few people who've touched this code to CC: in case they
have any ideas on working out how to disable the MMC function. If you
have contact with Ricoh directly or through a vendor, please ask them
for the PCI configuration writes needed to disable the MMC function on
this model so that you can read MMC cards with the SD interface instead.

The Toshiba laptops (R850) appeared to have similar problems, but it appears the Lenovo laptop mentioned here works with SD (but not MMC), and the Toshiba laptops don't work with either. A new bug has been opened for the Toshiba laptops (Intel and AMD R850) here: https://bugs.launchpad.net/bugs/773524

WRT to comment #7, that is from a conversation I had with upstream. We are still waiting on the BIOS vendor to tell is what magic to use with PCI configuration writes in the driver to turn off the MMC function in the controller. Unfortunately the bios vendor is located in Japan and they are not in a position to respond quickly.

This is still a problem in Natty, even after upgrading to linux-image-2.6.39-0-generic from kernel-ppa.

It's not a duplicate of 773524, after that bug is fixed Ricoh e823 card readers (multiple Thinkpad T420) still can't read SD cards. My thinkpad and comments 48 66 59 on bug 773524 confirm it.

Ondrej Mikle (d-mikle) wrote :

The reader is working with kernel 3.3.0 on Thinkpad T420 (I used Fedora kernel 3.3.0-8.fc16.x86_64, but I guess it should work with vanilla kernel as well). Hopefully it might help someone since it was quite PITA to find out how to make the reader work.
