Title:
  I/O errors prevent installing 15.04  to eMMC

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Installing Lubuntu Vivid x86_64 live CD via USB

  Voyo MiniPC  Z3735F CPU with Samsung MCGAFB 64GB eMMC

  Long before completion of file copying -- sometimes just during the
  initial disk scan --a flood of errors will occur, ending the install
  attempt.

  Files attached, but the errors basically look like this:
