  Mar 24 18:10:09 cygnus kernel: [19358.108509] lost page write due to I/O error on dm-0

  I can't recall the exact sequence of events, but I believe it was:

  * Inserted SD card. Prompted for passphrase. Entered and selected "remember passphrase forever"
  * Icon for SD card appeared on desktop with open padlock icon. Successfully accessed files.
  * Suspended and resumed laptop.
  * Was prompted again for passphrase for SD card. Again entered and selected "remember passphrase forever"
  * Got an error message dialog saying something to the effect that the file system was already mounted.
  * Icon for SD card appeared on desktop *without* padlock icon.
  * Right clicked on SD card icon and unmounted the drive.
