What about communicating it to the mainline kernel maintainer?

The patch was sent to our kernel maintainer. Still no response from him.

It does not do anything. No error, nothing. It is new (I know that has nothing to say) so it should actually work.

Now I tried a Transcend SDHC Card 16GB and no messages as well. I would be happy about an error message at least but nothing happens. Might the SDIO port be broken?

This is the message I get during boot time:
Code:
mmc0: mvsdio driver initialized, lacking card detect (fall back to polling)
so the kernel should have the correct modules, isn't it?

That answers that, then. I haven't tried a 16 gig card... I never did manage to get an 8 gig card working properly, either. I'm using a 4 gig right now.

I'm using 8GB kingston class 6 SDHC cards without any problems.

What kernel are you using?  I'm not running gentoo.  I'm running ubuntu on 2.6.30-rc4.

Have you tried any other mmc or sd cards?

I use the 2.6.30-rc4
I tried now two different SD-cards from different manufacturers and both are not working. Not even an error message.

It would be so much more helpful if for each card you, and anyone else posting their results, would identify
  • the manufacturer
  • the card trade name and capacity
  • the part number
  • the speed and speed class rating (e.g. Class 4, Class  6)
  • the file system (FAT 16 or FAT32) or whether you modified the file system (ext3)

See http://en.wikipedia.org/wiki/Secure_Digital_card
See also: http://www.newegg.com

Having all this information may help identify what kind of cards are having problems.

So the new mvsdio.patch for 2.6.30-rc4 broke my ability to read my sdcard.

I'm using a 8GB kingston class 6 SDHC card.

As I wrote:
[..] Transcend SDHC Card 16GB [..]
And it is a Class 6 card.
Currently it also crashes the complete system (reboot) when I put it into the slot. I do not think it is a matter of the filesystem because it does not work wide before any filesystem would be read.

In this case in my mind the card has some problems because even with the reader stick my host system has problems to read the informations to create the proper dev entry.

Any 16GB cards working by now?
