[SOLVED] SD card reader doesn't work (MX-16 on DELL Latitude 3150)

[MX-16_fan]

@Stevo, @Jerry3904, @all:

(...) To sum up, here's what I'll try out:

* Go to /etc/modprobe.d/, and create a file named "sd-card-fix.conf" there:

Code: Select all

sudo leafpad /etc/modprobe.d/sd-card-fix.conf

* Put the following line into that file: options sdhci debug_quirks2="0x10000" (instead of the frequently recommended "0x04", cf. https://bugzilla.kernel.org/show_bug.cgi?id=109231#c3).
* Save it.
* Rebuild the initramfs:

Code: Select all

sudo update-initramfs -u

* Reboot.

(...)

O.k., this works fine. mihail_bc wrote in his above posting that this works for him, too, so I am marking this "SOLVED".

Btw. it seems that actually fixing this kernel bug has troublesome implications, so the many owners of this card reader will probably be dependent on this workaround for quite some time. Let's hope that the kernel developers will produce a real fix in the future.

A big thank-you to all of you, and have a nice week, Joe

For whatever it is worth, none of these "fixes" work with my Dell Latitude 3160. As before, it will recognize an SD card 32 gig or smaller but nothing larger even with any of these work arounds.

Sorry to hear that. Does the DELL 3160 have exactly the same card reader as the 3150? If not, maybe it would make sense to open a separate thread for that.

In case anyone else has a Dell 3160 I finally figured out how to make linux recognize the sd card reader. Following the info above you need to change to the following:
sdhci debug_quirks2="0x65536"

Then the sd card reader works.

Cool, congratulations!

Hope that MX-17 will even support it out-of-the-box.
