Title:
  ext4 on mmcblk card causes major kernel problems

Status in linux package in Ubuntu:
  Won't Fix
Status in Debian GNU/Linux:
  New

Bug description:
  Release: Precise
  Architecture: i386

  Testcase:
  - Have a ext4 formatted partition on a mmcblk device mounted
  - Start a shell and change into a directory on that sd card
  - Suspend and Resume

  Result: Kernel fails to forcefully unmount the partition and produces
  a lot of errors because re-discovery of the filesystem runs into
  duplicate proc and sysfs files. fs is unmountable until the shell
  leaves the directory.
