[Bug 1514821] Re: SD card reader on Dell E7250 doesn't work in Ubuntu 15.10
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):
[ 92.252656] mmc0: new ultra high speed SDR104 SDXC card at address 0007
[ 92.252866] mmcblk0: mmc0:0007 SD64G 58.1 GiB
[ 92.255131] mmcblk0: p1
[ 92.471332] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)

whereas kernel 4.1.9-040109-generic shows the erroneous behaviour (three
line excerpt from dmesg, repeated 4 times):
[ 64.118346] sdhci: Timeout waiting for Buffer Read Ready interrupt during tuning procedure, falling back to fixed sampling clock
[ 64.120131] mmc0: tuning execution failed
[ 64.120136] mmc0: error -5 whilst initialising SD card

Thank you Blackgr for the hard work!
My SD card is a Kingston SD10VG2/64GB SDXC

Title:
SD card reader on Dell E7250 doesn't work in Ubuntu 15.10
Status in linux package in Ubuntu:
Confirmed
Bug description:
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
mmc0: tuning execution failed
mmc0: error -5 whilst initialising SD card
I was expecting to see the SD card mounted in the Unity actionbar,
like in 15.04.
