           Summary: Inserting Compact Flash Card on Thinkpad x31 mounts and
                    unmounts instantly
           Product: Ubuntu
           Version: unspecified
          Platform: i386
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gnome-volume-manager

When I insert a Compact Flash card into the built-in slot on my IBM Thinkpad x31
behaviour is strange.

The first time I insert the card after a reboot, it is recognized and mounted
correctly, and the icon appears on the desktop.
After umounting and removing the card, the strange behaviour occurs. If I
reinsert the card (or a different card) a second time, the device is recognized,
and mounted, and the icon shows up for a fraction of a second, but then the card
is instantly unbmounted again.

When this happens, I can sometimes get the card mounted as rott, either throught
the command-line or using the disks-admin utility. However equally often the
disks-admin utility will freeze in this situation, and any further attempt to
access or mount the device seem to freeze. Once in this state, I cannot mount
usb devices or anything else for that matter, and if I try to shutdown the PC,
the shutdown process freezes partway, and I need to hard reboot it.

Also, once the laptop is in this state, i.e. after mounting and then unmounting
a compact-flash card, other tasks, such as suspend-to-ram (or more often,
resume) are also likely to freeze up the laptop.

I have followed the instructions on the wiki-page DebuggingRemovableDevices and
attached the requested files to this bug-report. There are 2 sets of these
files. The first set is for the correct mounting and unmounting and the second
set is for the second attempt, when things go wrong.

This laptop is running a newmy reinstalled Ubuntu Breezy with Gnome.

Here is the output from the id and uname commands.
