[Bug 1514821] Re: SD card reader on Dell E7250 doesn't work in Ubuntu 15.10

 

dexter1, the next step is to fully commit bisect from kernel 3.19 to 4.2
in order to identify the last good kernel commit, followed immediately
by the first bad one. This will allow for a more expedited analysis of
the root cause of your issue. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  SD card reader on Dell E7250 doesn't work in Ubuntu 15.10

Status in linux package in Ubuntu:
  Incomplete

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.
