I/O Errors with O2Micro sdhci PCI MMC/SD host controller v2

Looks like similar issues affects/affected the Acer Aspire 310 also...

Hmm, I have the exact same problem on a Dell Vostro 1710 :( Any updates on your situation?

I the reporter don't have any progress on this matter. I'm using an external USB SD card reader to work around the issue for now. Would be nice to have it fixed.

In Ubuntu Jaunty [release version] on Dell Vostro 1710 [same hardware] I see different behaviour from Intrepid. On Jaunty insertion of an SD or MMC card results in absolutely nothing. No dmesg output...nothing as far as I can see. On Intrepid, the MMC card worked, but now with Jaunty, I see nothing whatsoever.

In Jaunty demsg output:

Acer Extensa 4420-5963 and Toshiba A300-15J have the same O2Micro controller (v2).

I confirm the same issue with jaunty(9.04) on MSI GX700. It uses the same controller and again inserting a card results in absolutely nothing.
It was working for me in feisty(7.04) and nothing ever since.
I would really like to see this issue fixed.

I get the same on my MSI GT725 -same controller.

the same...

add:

Code:

blacklist sdhci-pci
blacklist sdhci
blacklist mmc_core

to /etc/modprobe.d/blacklist.conf

this solve the problem ?

Hi dcam,

Please be sure to confirm this issue exists with the latest development release of Ubuntu. ISO CD images are available from http://cdimage.ubuntu.com/releases/lucid . If the issue remains, please run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 323159

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[This is an automated message. Apologies if it has reached you inappropriately; please just reply to this message indicating so.]

I've just boot up the 2.6.33 kernel, and the problem with SD card gone. Have no MMC or XD cards to test. So it seems like the latest kernel fixes this issue.

dcam,
    Can you confirm if this is resolved per Seva's comment?

Thanks!

As per my above comments, and despite comments since from others It is working for me in 2.6.28-18-generic (jaunty). I tested a lucid CD boot and it worked too, although it still says:

[ 85.818320] mmc0: Unknown controller version (2). You may experience problems.

Is there some sort of file copying test suite I could run over it? I seem to remember that although it works, that there may be some transient issues with reliability.

This issue still happens in the latest ubuntu lucid kernel 2.6.32.19.20.

here is the lspci output:

Maybe it's not a problem related with a specific controller? I also have the "unknown controller version" problem with my Dell Latitude E6510, but it is a Ricoh controller:

This link is no longer available and if another can't be found then this possible fix is no longer a fix.

Did a Google search for the file and found nothing... still searching...

Any help with this would be appreciated.
