I have found a workaround for the SD card controller in my DELL Latitude 7250
with a SDXC card. I came accross this page:
http://www.0xf8.org/2016/01/workaround-for-broken-o2-micro-sd-card-reader-support-since-linux-kernel-version-4-1-8/
By setting "sdhci.debug_quirks2=0x4" as default kernel para
I have a DELL E7250 Latitude and after the upgrade from 15.04 my SD
cardreader cannot read the Kingston 64GB SDXC anymore. Same error
messages in dmesg:
[1.886833] sdhci: Timeout waiting for Buffer Read Ready interrupt during
tuning procedure, falling back to fixed sampling clock
[1.88861
Public bug reported:
My experience with the SD card is the same as experienced by Simon James Greer
in bug #1509119
Christopher M. Penalver notified me that i would be ok to subscribe him to this
report.

Title:
SD card read
I tried the latest mainline linux kernel for wily: no sd-card and the same
errors in dmesg.
Oddly enough, an older 3.19.0-31 kernel which was still in my grub list also
showed the same behavior. I cannot recall this happening when i used 15.04
vivid.
I booted from a live stick with 15.04 and th
** Description changed:
I booted the machine with the SD card removed. I logged into Unity, inserted
the SD card and saw the error messages popping up in dmesg:
sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning
procedure, falling back to fixed sampling clock

I've updated the BIOS to version A08

... but it does not address the issue: The SD card still cannot be found, even
after taking it out and re-inserting.
Same messages in dmesg as previously noted:
I've updated the bios to version A09 today and checked if the problem
still exists. It does.
So with the information from Blackgr i tested the two kernel versions
and i can indeed verify that kernel 4.1.8-040108-generic reads mt SDXC
card just fine (four line excerpt from dmesg):

in tonight, but it looks like
the same issue.
Well done though :) Keep at it!
Yours sincerely,
