Comment(by eeksock):

 I'm actually seeing this all the time now in the Update.1-690, presumably
 because of the much more frequent suspension.

 1. Insert an SD Card, open a Terminal.

 2. Launch Read on a PDF from the Journal.

 3. Wait until Read suspends.

 4. Go back to the Journal.

 --> SD Card has disappeared (or repeat as necessary)

 5. Go to the terminal, and enter "df" to verify that the card failed to
 remount

 6. The last few lines from my dmesg look like this:

 [ ... ] ac97 0-0:AD1888: resuming
 [ ... ] olpc-dcon: The CPU has control
 [ ... ] Restarting tasks ... done.
 [ ... ] PM: Adding info for mmc:mmc0:b368
 [ ... ] mmcblk0: mmc0:b368 SD     1960448KiB
 [ ... ]  mmcblk0: p1

 Manually mounting /dev/mmcblk0p1 from the Terminal works, but Journal
 doesn't pick it up.
