Title:
  sd card reader on mac book pro retina 11,1 slow to read from

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I recently plugged a few SD cards into the reader on a new Mac Book
  Pro retina late 2013 (11,1) and experienced a serious slowness in
  loading its contents in nautilus. When I ran dmesg on a console I saw
  there had been a bunch of storage errors from scsi and the filesystem.
  The cards I used were a SanDisk Ultra 32GB HC I microSD card and a
  Lexar  Professional 32GB SDHC class 10 card. Both were very slow to
  read from. I did not try to write to either of them.
