SD card reader problem

Hi, I can't get working internal SD card reader in my Dell E6400 laptop.
When I plug in the SD card, this is output of dmesg:

...

...

That last section repeats many times in dmesg. Then I can see device /dev/mmcblk0, but I cannot mount it:

$ sudo mount /dev/mmcblk0 ~/tmp/test/
mount: /dev/mmcblk0 is write-protected, mounting read-only
mount: /dev/mmcblk0: can't read superblock

I have tried two SD cards, 2GB and 6GB SDHC, both do the same and both work under Windows. Any idea where is problem? Thanks.

Re: SD card reader problem

What kernel are you running?  I have not seen problems like that in any 3.x kernel.  Here is where I remove and install my card, plus the lspci details on my hardware.

Re: SD card reader problem

I have custom kernel, but it is based on stock Arch Linux kernel, the only difference is tha I have enabled CAN support.

[ondra@dell ~]$ uname -a
Linux dell 3.12.2-1-custom #1 SMP PREEMPT Thu Dec 5 14:01:26 CET 2013 x86_64 GNU/Linux

Also tried stock Arch Linux kernel

Linux dell 3.12.6-1-ARCH #1 SMP PREEMPT Fri Dec 20 19:39:00 CET 2013 x86_64 GNU/Linux

and this is my adapter

[ondra@dell ~]$ lspci -nn | grep SD
03:01.2 SD Host controller [0805]: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter [1180:0822] (rev 21)

Re: SD card reader problem

I see somewhat similar errors but only during boot (quite frequently). I'm using luks and I store the keys on a sd card, during boot and after the keys have been read properly, sometimes I see lots of errors similar to yours.

After the system has finished booting, the card reader works fine and I don't see any errors. What I have noticed is that if I reboot with a card in the card reader it isn't detected after the reboot, I have also found that (in my case) I can hang the machine if I insert a card after the machine has been turned on and the kernel has not finished loading. It seems that either the card reader, the bios or the specific implementation have some bug that causes problems.

I tried just now to remove and reinsert a card and I also saw errors similar to yours and the card didn't get detected, on a 2nd and 3rd try it worked without errors.

I don't have any good suggestions to give you, what _might_ help is if you pass any quirks to sdhci, I've tried to look into it before but didn't find any document explaining what those quirks are, I suppose you would need to dive into the code and figure out what the quirks are (my knowledge of C and my motivation were not enough to do it myself).

lspci -nn | grep SD
07:01.1 SD Host controller [0805]: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter [1180:0822] (rev 22)

Edit:
I hope this edit doesn't bump the thread but I have some info that might help someone in the future.
The errors I was seeing, and another problem I was having, are gone after blacklisting r592 and memstick. I know it isn't the ideal solution but at least for me memory sticks never worked very well with this card reader so not a big loss.
