Assigning to the kernel for now, as that looks like a block device
driver issue at first sight.

Title:
  I/O errors on mmc partitions

Status in linux package in Ubuntu:
  New

Bug description:
  Running live USB of the latest Vivid daily build on Lenovo Thinkpad 10
  with Samsung eMMC MDGAGC 116 GiB:

  Ubuntu 15.04 (vivid-desktop-amd64.iso 2015-02-16 8:05)
  Linux 3.18.0-13-generic
  systemd 218-10ubuntu1

  Extract of dmesg (full log in attachment):

  [ 12.337332] mmc0: BKOPS_EN bit is not set

  [ 12.376682] mmcblk0: p1 p2 p3 p4

  I get multiple errors when trying to access to mmc partitions:

  Ubiquity reports "Input/output errors" consequently, I'm unable to
  install Ubuntu on mmcblk0 device.

  I don't know if it's related, but I also get a warning from libparted:

  sudo parted -l
  Warning: The driver descriptor says the physical block size is 2048 bytes, but
  Linux says it is 512 bytes.
